What must I do to be saved?
The most important question you will ever ask
Few questions matter more than this one,
"…Sirs, what must I do to be saved?"
These words were spoken by the Philippian jailer after a dramatic encounter with God. Having witnessed the faith of Paul and Silas, experienced an earthquake that opened the prison doors, and realised that God Himself was at work, the jailer was overcome with one pressing concern. He did not ask how to become happier, more successful, or more religious. He asked the question every person must eventually answer:
What must I do to be saved?
Paul and Silas's answer was wonderfully simple:
"Believe in the Lord Jesus [as your personal Savior and entrust yourself to Him] and you will be saved, you and your household [if they also believe]."
This answer has echoed throughout history. Salvation is not earned through good works, religious rituals, or moral improvement. It is God's gracious gift, made possible through the death and resurrection of Jesus Christ and received through faith in Him.
So, going back to the basics what does it actually mean to believe in the Lord Jesus Christ?
To answer that, we must listen to Jesus Himself.
Why do I need to be saved?
God created humanity in His own image (Gen 1:26–27), to know Him, love Him, enjoy fellowship with Him, and live under His good and perfect rule. But instead of trusting our Creator, humanity chose to reject Him. We wanted to decide for ourselves what was right and wrong. The Bible calls this sin.
Sin is more than breaking God's commands - it is rejecting His rule and living as though we know better than He does. Because God is perfectly holy, sin has real consequences. It separates us from the God who is the source of life.
Although we may be physically alive, apart from Christ we remain spiritually dead. Sin has broken the relationship we were created to enjoy, and no amount of self-improvement, religious effort, or moral achievement can restore it.
Since all have sinned and fall short of the glory of God.
This is why salvation is necessary. Only God can do for us what we could never do for ourselves.
What it means to be born again
When Jesus spoke with Nicodemus, a respected religious leader, He said something that must have come as a shock, "I assure you and most solemnly say to you, unless a person is born again [reborn from above - spiritually transformed, renewed, sanctified], he cannot [ever] see and experience the kingdom of God" (John 3:3).
Nicodemus was sincere, moral, and deeply knowledgeable about the Scriptures. Yet Jesus told him that religion, knowledge and good intentions were not enough.
He didn't need a better version of his old life - he needed an entirely new life.
The same is true for every one of us. This is why salvation is far more than forgiveness - it is a supernatural work of God.
Jesus explained, "That having been born of the flesh is flesh, and that having been born of the Spirit is spirit" (John 3:6). Just as our physical life began with a physical birth, our spiritual life begins when God's Spirit gives us new life from above.
When a person turns to Christ in repentance and faith, God forgives their sins, gives them His Holy Spirit, and makes them spiritually alive. This new birth is not simply adopting new beliefs or trying harder to live a better life. God changes us from the inside out, giving us a new heart, a new identity, and a restored relationship with Himself.
Later in the same conversation, Jesus also revealed the reason why new birth is possible - God's desire is not to condemn people but to rescue them through His Son.
For God so loved the world that He gave His one and only Son, that everyone who believes in Him shall not perish but have eternal life.
For God did not send His Son into the world to condemn the world, but to save the world through Him.
Can I earn my salvation?
Because salvation is a work of God, it cannot be earned by human effort.
Many people assume that if they are good enough, kind enough, or religious enough, God will accept them. The Bible teaches the opposite. No amount of good works can erase sin or make us spiritually alive. We cannot save ourselves any more than a dead branch can make itself live again.
Salvation is entirely an act of God's grace. Jesus did everything necessary through His perfect life, sacrificial death, and victorious resurrection. We simply receive what He has accomplished.
For it is by free grace (God's unmerited favor) that you are saved (delivered from judgment and made partakers of Christ's salvation) through [your] faith. And this [salvation] is not of yourselves [of your own doing, it came not through your own striving], but it is the gift of God; Not because of works [not the fulfillment of the Law’s demands], lest any man should boast. [It is not the result of what anyone can possibly do, so no one can pride himself in it or take glory to himself.]
Salvation is not something we achieve. It is something we receive freely by the grace of God.
How do I respond to Jesus?
Although salvation is God's work, Scripture repeatedly calls people to respond to Him. Throughout the New Testament, that response is described with two words - repent and believe.
What does it mean to repent?
To repent literally means to change your mind, but biblical repentance is much deeper than simply changing an opinion. It is a change of heart that leads to a change of direction.
Imagine you're walking down a road that leads away from God. To repent is to stop, recognise you're heading the wrong way, turn around, and begin walking towards Christ instead. It is leaving behind a life centred on yourself and beginning a life centred on Jesus.
Repentance means acknowledging that God is right and we are wrong. We stop justifying our sin, making excuses, or trying to live life on our own terms. Instead, we humble ourselves before God, ask for His forgiveness, and willingly surrender our lives to Him.
This doesn't mean you become perfect overnight. Every Christian continues to battle temptation and grow in holiness (this process is called sanctification). But repentance does mean there has been a decisive change in direction. The old life is no longer the life you want to live.
In practical terms, repentance looks like someone who once loved sin beginning to hate it. It means forgiving instead of holding onto bitterness, pursuing purity instead of immorality, choosing honesty over deceit, and seeking God's will instead of insisting on our own.
Repentance is not cleaning yourself up before coming to Jesus. It is coming to Jesus because you know you cannot clean yourself up. Jesus never called people merely to add Him to an already busy life. He called them to deny themselves, take up their cross, and follow Him.
What does it mean to believe?
When Paul told the Philippian jailer, "Believe on the Lord Jesus Christ, and you will be saved," he was describing far more than intellectual agreement. Many people believe Jesus existed. Many believe He was a great teacher. Some even believe He is the Son of God. But that alone is not saving faith.
You believe that God is one; you do well [to believe that].
The demons also believe [that], and shudder and bristle [in awe-filled terror - they have seen His wrath]!
The demons have no doubt about who Jesus is. They know He is the Son of God. They know He died and rose again. They know He has all authority. Yet they do not worship Him, trust Him, love Him, or submit to Him.
Knowing facts about Jesus is not the same as belonging to Jesus.
Saving faith is personal trust. It means placing your confidence entirely in Jesus Christ - trusting that His death on the cross paid for your sins, believing that He rose from the dead, and relying completely on Him rather than your own goodness, religious efforts, or achievements.
Faith is not simply saying, "I believe Jesus is Lord." It is living as though He actually is.
To believe in Jesus is to entrust your life, your future, your forgiveness, and your eternity to Him. It is choosing to rely on Him every day instead of relying on yourself.
Can I accept Jesus as saviour but not Lord?
The Bible never presents Jesus as merely someone who improves our lives or helps us achieve our own goals.
He is Lord.
To receive Christ is to welcome Him as both Saviour and King. We gladly receive His forgiveness because of what He accomplished on the cross, and we willingly submit ourselves to His authority. This doesn't mean Christians obey perfectly from day one. We all have much to learn (a process described in Romans 12:2 called renewing the mind), and God patiently transforms us over time. But it does mean we have a new Master.
Instead of asking, "What do I want to do?," we begin asking, "What does Jesus want me to do?" Instead of shaping Jesus into our image, we allow Him to shape us into His.
This is why Paul told the jailer to believe in the Lord Jesus Christ. Jesus is not only the One who saves us from sin. He is the One we now follow. Following Jesus is not simply agreeing with His teaching - it is surrendering our lives to His leadership, trusting Him enough to obey Him and walking with Him for the rest of our lives.
What happens when I'm saved?
Salvation is not merely a change in our eternal destination. It is a work God performs in us. When someone responds to Christ in repentance and faith, God performs a work that no human being could ever accomplish. He forgives every sin. The guilt, shame, and condemnation that once separated us from Him are removed because Jesus has already paid the penalty on the cross.
He gives us His Holy Spirit.
Instead of remaining spiritually dead, we become spiritually alive. God Himself comes to dwell within His people, empowering them to know Him and walk in obedience.
He adopts us into His family. We are no longer enemies or strangers. We become sons and daughters of God, receiving a new identity and belonging to His household.
He makes us a new creation. As Paul writes, "Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." (2 Cor 5:17)
Salvation is not simply receiving a future home in heaven. It is receiving the very life of God now. Everything begins to change because we have been united with Christ.
How can I know if I am truly saved?
The new birth produces new life. Christians do not become perfect overnight. There is still a lifelong process of growing in holiness and becoming more like Jesus.
Jesus taught that a tree is recognised by its fruit.
In the same way, those who have been born of God's Spirit begin to display the character of Christ.
While every Christian grows at a different pace, Scripture points to several evidences that God is at work:
- A growing love for Jesus.
- A desire to know and obey God's Word.
- A willingness to turn away from sin.
- Increasing humility and dependence upon God.
- Love and compassion toward other people.
- The fruit of the Holy Spirit becoming increasingly evident.
- A growing desire to share the Gospel and make disciples.
- A longing to live for God's Kingdom rather than your own.
These things do not earn you salvation. They are the fruit of salvation.
An apple tree does not become an apple tree because it produces apples. It produces apples because it already is an apple tree. Likewise, genuine spiritual fruit is the evidence of the new life God has already given.
What should I do after becoming a Christian?
Salvation is not the finish line. It is the beginning of a completely new life. Jesus calls every believer not only to believe in Him, but to follow Him. The Holy Spirit who gives us new birth also teaches us to walk in obedience, grow in holiness, love others, proclaim the Gospel, and participate in the mission Jesus entrusted to His followers.
Like a newborn child, every Christian is called to grow. We learn to read and obey God's Word. We spend time with our Father in prayer. We are baptised as Jesus commanded. We become part of a community of believers.
We learn to serve others with love and humility. We share the hope of Christ with those around us.
And as we continue walking with Jesus, He transforms us to become more like Himself.
Will I respond to Jesus today?
When the Philippian jailer asked, "What must I do to be saved?" the answer was not a list of religious achievements. It was Jesus Christ. "Believe on the Lord Jesus Christ, and you will be saved" (Acts 16:31).
That invitation remains open today.
If you recognise your need for God, turn from your sin and place your trust in Jesus Christ. Receive Him as your Saviour. Follow Him as your Lord.
The God who calls you is also the God who gives new life.
The God who forgives you is also the God who transforms you.
Salvation is not the finish line of the Christian life - it is the beginning.
The same Jesus who forgives our sins also calls us to follow Him. He teaches us to deny ourselves, take up our cross daily and become His disciples.
The Holy Spirit who gives us new birth also empowers us to grow in holiness, love others, proclaim the Gospel and make disciples.
If you have turned to Christ, please don't stop at simply believing facts about Him. Walk with Him. Learn from Him. Obey Him. The God who saves you is also the God who transforms you into the likeness of His Son.
