John 3:16 says, "For God so loved the world, that He gave His only begotten Son, that whosoever believeth in Him should not perish, but have everlasting life."
Paul was asked, "What must I do to be saved?" in Acts 16:30. Paul gave the answer in verse 31 as "Believe on the Lord Jesus Christ, and thou shalt be saved." To be saved or to be born again is as easy as praying ABC.
A - Acknowledge and Accept the fact that you are a sinner and the price of sin is death, that is an eternal separation from God. (Rom. 3:23; Rom. 6:23)
B - Believe on the Lord Jesus Christ. He is the gift of God that paid the price of sin for you and me. (John 3:16; Rom. 6:23; Rom. 5:8; Eph. 2:8-9)
C - Call and Confess from the heart to God in prayer the fact that you are a sinner and you believe that Jesus Christ paid the price of sin and has risen from the dead that you might have eternal life through Him. (Rom 10:9-10, 13)
