When a desperate man asked how to be saved, Paul did not give him a list of works. He gave him Christ.
Few questions are more important than this:
"What must I do to be saved?"
— Acts 16:30
In Acts 16, a desperate jailer asked that very question. The answer he received is one of the clearest presentations of the Gospel in the Bible.
This scene connects naturally with the broader biblical answer to what a person must do to be saved: believe on the Lord Jesus Christ.
Paul and Silas had been beaten, imprisoned, and placed in stocks. Yet instead of despairing, they prayed and sang praises to God.
"And suddenly there was a great earthquake, so that the foundations of the prison were shaken: and immediately all the doors were opened, and every one's bands were loosed."
— Acts 16:26
The jailer awoke and assumed the prisoners had escaped. But Paul cried out:
"Do thyself no harm: for we are all here."
— Acts 16:28
The jailer rushed in trembling and fell before Paul and Silas.
Then he asked:
"Sirs, what must I do to be saved?"
— Acts 16:30
Notice what he did not ask. He did not ask how to become more religious. He did not ask how to earn God's favor. He did not ask how to begin a lifetime probation process.
He asked how to be saved.
Paul and Silas answered immediately:
"Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house."
— Acts 16:31
Notice what they did not say.
They gave one condition:
Believe on the Lord Jesus Christ.
Many modern presentations of salvation are far more complicated than Paul's answer.
But Paul was speaking to a man whose eternal destiny was at stake. If additional requirements were necessary, this was the moment to mention them.
Instead, Paul pointed the jailer to Christ.
This agrees perfectly with John 6:47, where Jesus said the one who believes on Him has everlasting life.
To believe is to be persuaded that Jesus is who He claimed to be and that His promise is true.
The jailer was not being asked to trust in himself. He was being asked to trust in Christ.
Salvation rests on the finished work of Jesus, not on human effort. That is why the believer can have assurance and why salvation cannot be lost once received as God's gift.
Later in the chapter, the jailer was baptized. But notice the order.
First he heard the word of the Lord. First he believed. Then he was baptized.
Baptism followed faith. It did not replace faith, and it did not become the condition for eternal life.
This is why water baptism is not required for salvation, even though it is an important public testimony.
The jailer's answer is consistent with the rest of Scripture.
Jesus said the believer has everlasting life and shall not come into condemnation.
Jesus told Martha that the one who lives and believes in Him shall never die. In John 11:25–26, the issue was simply whether she believed Him.
The thief on the cross had no time to perform religious works, yet Jesus promised him Paradise.
Again and again, faith in Christ is presented as the condition for receiving eternal life.
Many people struggle with the simplicity of the Gospel. Human nature wants to contribute. We want to earn. We want to deserve.
But the jailer's question received a direct answer.
God did not make salvation complicated. People often do.
The Philippian jailer asked the greatest question a person can ask:
"What must I do to be saved?"
Paul gave the answer:
"Believe on the Lord Jesus Christ, and thou shalt be saved."
No list of religious requirements.
No probationary period.
No confidence in human performance.
Just faith in the Savior.
The answer that saved the Philippian jailer is the same answer God offers today.
Believe on the Lord Jesus Christ, and thou shalt be saved.
