Trust the good news about Jesus
The centre of Christian faith is not a list of achievements. It is Jesus himself. Paul reminded the Corinthian church that Christ died for sins, was buried, and rose again. These are not side details. They are the good news on which Christian hope rests (1 Corinthians 15:3-4).
To believe means more than agreeing that Jesus existed or knowing the Easter story. It means placing your confidence in him. Jesus speaks of eternal life being given to those who believe in him, and John describes receiving Christ as becoming one of God’s children (John 3:16; John 1:12).
For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:
Believe that Jesus is Lord
Romans 10 connects salvation with trusting in your heart that God raised Jesus from the dead and confessing Jesus as Lord (Romans 10:9-10). Calling Jesus Lord means recognising who he is and yielding yourself to him. It is personal trust, not just religious information.
That trust can begin with very simple words. You can tell God that you need his mercy, that you believe Jesus gave himself for you, and that you want to belong to him. God is not waiting for a polished speech. The tax collector who simply asked for mercy went home accepted by God, while the outwardly impressive Pharisee trusted his own righteousness (Luke 18:13-14).
That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.
Receive grace, not a reward
You cannot earn salvation by being kind enough, attending church often enough, or fixing every part of your life first. Paul says salvation comes by grace through faith, not by works, so nobody can boast before God (Ephesians 2:8-9). Grace means God gives what we could never deserve.
This does not make good choices unimportant. God’s grace changes people, and believers are called to live in a way that reflects their new life. But changed living is the fruit of salvation, not the price of admission. Jesus came to call sinners, which means you do not need to pretend you are already well to come to him (Mark 2:17).
Turn towards God and keep following
Faith includes repentance. Repentance is a change of mind and direction: turning from sin and self-rule towards God. When Peter spoke to the people in Jerusalem, he called them to repent and turn back so that their sins could be forgiven (Acts 3:19). Nobody does this flawlessly. The point is the direction of your trust and life.
Some Christians place different emphasis on the timing and meaning of baptism, but Christians broadly agree that baptism is a meaningful response of obedience for someone who has put their faith in Christ. Start with Jesus. Read one of the Gospels, such as John, ask God to help you know him, and share your faith with a trusted local Christian community.
