For all have sinned, and come short of the glory of God (Ro 3:23)
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. (Ro 6:23)
Jesus came into Galilee, preaching the gospel of the kingdom of God, and saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel. (Mk 1:14b-15)
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. (Ro 10:9)
To accept Jesus as Savior, pray:
I recognize that I am a sinner. I choose by faith to abandon my sin and receive Jesus, his death, and resurrection, for forgiveness and cleansing of my sins. Fill me with Your Spirit. Enable me to meet any requirement You have for me as Your new child.
Then go and tell your decision to someone, preferably another Christian.
