The Bible tells us that we were born in sin and separated from God. (Romans 3:23)
The Bible informs us that God is not willing that any should perish but that all should come to repentance. (2 Peter 3:9)
The Bible shows us that nothing we can do will earn our salvation but that it is the gift of God… not of works, lest anyone should boast. (Ephesians 2:8-9)
The Bible teaches us that the only payment for our sins was Jesus Christ’s death on the cross. (1 Peter 2:24)
The Bible reveals to us that beside being fully man, he is fully God, and his one death had the power to cleanse all of us of our sin. (Philippians 2:8)
The Bible promises us that everyone who calls on His name will be saved. (Romans 10:13)
Merely tell God that you know you are a sinner and that you need him. Accept the gift of salvation, believe that Christ is risen, and say so.
If you turn from your sin and you confess with your mouth the Lord Jesus and believe in your heart that God has raised him from the dead, you will be saved.
