The most important decision you will ever make in your life is where you will spend eternity.  Do you know where you will spend your eternity?  None of us can be good enough to get to heaven because, "As it is written, There is none righteous, no, not one." Romans 3:10

That is why God sent His only begotten son to this earth.  "But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us." Romans 5:8

You need to repent of your sin and trust Christ as your personal Saviour.  "Except a man be born again, he cannot see the kingdom of God." John 3:3

You must recieve by faith Jesus as your own personal Saviour.  "For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:  Not of works, lest any man should boast." Ephesians 2:8, 9

Tell Jesus in your own words that you know you are a sinner and need His forgiveness.  "That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him [Jesus] from the dead, thou shalt be saved." Romans 10:9, 10

Once you have received the Lord Jesus Christ as Saviour, you need to be: baptized by immersion, begin reading your Bible and praying daily, be discipled, tell others about Christ, and attend and unite with a sound Bible-believing, gospel preaching church.
