"A" stands for Admit. A person must admit to God that she is a sinner. She must be sorry for her sin and turn away from sinning. Verses that support this step are Romans 3:23; Romans 6:23; Acts 3:19; and 1 John 1:9.
"B" stands for Believe. A person must believe that Jesus is God's Son and that God sent Jesus to pay the penalty for sin. Verses about believing include John 3:16; John 14:6; and Romans 5:8.
"C" stands for Confess. A person must confess her faith in Jesus Christ as Savior and Lord. Read Romans 10:9-10, 13.
After a person admits to God that she is a sinner, repents and turns from her sin, believes that Jesus is God's Son sent to die to pay for the sins of the world, and confesses that faith in Jesus, she is a Christian and knows Jesus as her Savior.
Remember: It is not your job to "save" your child - it is God's! However, as a parent you have the responsibility (and privilege) of guiding your child to faith in Christ. Pray that God will give you the wisdom to teach your child about Him. Then know that you can only do this with His help and thank Him for His guidance. After all, He loves your child even more than you do!
The following is a sample prayer to use as a guide for praying with your child:
Dear God, thank You for choosing to love me! I know I am a sinner. I believe You sent Your Son, Jesus Christ, to die for my sins. I believe He rose again and lives today. Today, I repent and turn away from my sin. Thank You for Your wonderful love and for changing my life forever. In Jesus' name I pray, Amen.
