In the letter written to the Romans Paul argues that it is written in the "laws", that because he was circumcised (which was a Jewish right of passage) Moses' heirs would have an automatic pass into heaven. That circumcision was all that was required for God to grant that pass. Because through faith and works which circumcision showed, it to be,this would be so. Paul questions this. What of the Gentiles(regular men & women)? He argues that through Davids lineage, the same applies. Jesus is a decedent of David. And Jesus was circumcised like Moses. And through Jesus all men have the same chance to enter into the kingdom. By works we are judged and sin is looked upon as sin. But again Jesus died for those sins. Gods law is meant to be followed yes, but so many fail, and will continue to do so. We need to repent, ask forgiveness. Practice loving unconditionally without prejudice, and without judgement, and remember that God gave his only son for us.
Romans 4:7-8 Blessed are those whose lawlessness deeds are forgiven, and whose sins are covered. Blessed is the man to whom the the Lord shall not impute sin.
