The Romans' Road
The reason we can't go to heaven:
Romans 3:10(KJV) "As it is written, There is none righteous, no, not one:"
Romans 3:23(KJV) "For all have sinned, and come short of the glory of God;"
Where sinners go:
Romans 6:23(KJV) "For the wages of sin is death(Second Death); but the gift of God is eternal life through Jesus Christ our Lord."
The second death?
Revelation 20:14(KJV) "And death and hell were cast into the lake of fire. This is the second death."
Romans 5:8(KJV) "But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us."
Romans 10:9-10(KJV) "(9)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. (10)For with the heart man believeth
unto righteousness; and with the mouth confession is made unto salvation."
Romans 10:13(KJV) "For whosoever shall call upon the name of the Lord shall be saved."
What to do:
Realize that you are a sinner on your way to hell. Realize that Christ died for your sins and ask Him to forgive you of your sins and save you. You can do this through prayer and mean it.
