People usually ask this question for one of two reasons. Some remember a church moment but are unsure what it meant. Others believe in Jesus and still wake up on a bad Tuesday wondering whether any of it is real. Both deserve a straighter answer than “you’ll just know.” Feelings are terrible paperwork.
Start with the question in Acts 2
The crowd at Pentecost had heard that Jesus, whom they crucified, was both Lord and Christ. They were cut to the heart and asked Peter and the other apostles, “Brothers, what shall we do?” (Acts 2:37). Peter answered:
“Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.” (Acts 2:38)
The message they had already heard called them to believe that Jesus is the Christ, the Son of God (Acts 2:36; John 20:31). Their response was repentance, baptism, and the promised gift of the Holy Spirit. About three thousand accepted the message and were baptized that day (Acts 2:41).
That gives you something solid to examine. Do you believe Jesus is the Son of God and trust Him as Lord? Have you turned toward Him? Were you immersed in water as your own response of faith? Are you relying on His promise of forgiveness and the Holy Spirit?
God’s promise is steadier than your mood
Some days faith feels close enough to touch. Other days your prayers bounce around the room. The promise in Acts 2:38 does not include an emotional test. Peter did not say, “Repent, be baptized, and maintain a constant sense of certainty.” He pointed to what God said He would do. If prayer feels empty and faith feels exhausting, read what to do when you do not feel close to God.
John wrote his first letter so believers could know they have eternal life (1 John 5:13). He also spoke plainly about walking in the light, confessing sin, loving other people, and obeying Jesus. Those things do not purchase salvation. They are signs of a life that has actually turned toward Him.
If you skipped a step
Maybe you prayed years ago but were never baptized. Maybe you were baptized before you personally believed. Maybe repentance was never explained beyond “feel bad.” You do not need to defend the past. Read Acts 2:36-41 and Acts 8:26-39, then respond to what you now understand.
Repentance means turning around. Baptism is full immersion in water as a believer. Any follower of Jesus can help baptize you; no stage, paid pastor, or membership class is required. Find your city if you want help finding water and another believer. It is free, and nobody will ask you for money.
Where to begin today
Start reading the Gospel of Matthew, which follows Jesus from the beginning of His public life through His death and resurrection. You can read, watch, or listen free at GotLuv.org. Read John next; John tells you why he wrote: “that you may believe that Jesus is the Christ, the Son of God” (John 20:31).
Then keep going with other believers. The people baptized in Acts 2 devoted themselves to the apostles’ teaching, fellowship, breaking bread, and prayer (Acts 2:42). Assurance grows in that ordinary life together. Usually around a table.
