Romans 2:13

For not the hearers of the law are just before God, but the doers of the law shall be justified.

This verse is about the futility of doing the law because no one could keep it. That is why Jesus came to this earth to die as a sin substitute so that we could gain salvation. Work could never substitute the sacrifice of the Lamb. The hardest part for most people is to believe that Jesus is willing to make us righteousness. Just believe and let God work the miracles in your life.
