The reason it's called the "Roman Road to Salvation" is because in the book of Romans, written by the apostle Paul, are several "steps" that lead to belief in Christ and therefore salvation.
1~As it is written, There is none righteous, no, not one. Romans 3:10 No one is able to get to heaven on his or her own.
2~For all have sinned and fall short of the glory of God. Romans 3:23 The Bible tells us that we all have sinned. We all fall short.
3~For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. Romans 6:23 We earn death because of our sin. We deserve Hell. We can have the free gift of eternal life in Heaven only through Jesus Christ
4~But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. Romans 5:8 Because of His love the Father sent His Son Jesus to die and pay the penalty for our sins, even though we don't deserve it
5~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. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. Romans 10:9-10 A person receives God's free gift of love and life by placing faith in Jesus Christ. To believe is simply to take God at His word. With our heart we believe that Jesus is God's Son who died for our sin on the cross and arose from the grave to live in us as Savior and Lord.
6~For whosoever shall call upon the name of the Lord will be saved. Romans 10:13 Any person who will call upon the name of Jesus, the Lord, shall be saved. To call means simply to ask in prayer. The verse does not require one to know more... do better... clean up one's life... or in any way try to add to what Jesus has done for us
Just remember the words of Ephesians 2:9 -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.
