Romans 5 “19 For just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous.”
Man cannot be righteous by obeying works because they fail.
God told Adam to do ONE thing and he failed.
Just imagine that: man cannot even do one thing that God commanded.
Therefore man cannot DO works to be righteous. It is impossible to be righteous by our deeds.
But Jesus Christ obeyed ALL the works of the law, dying on the cross.
He was obedient till death on the cross.
He forgave our sins.
He rose from the dead.
We are Righteous by faith in Christ through His obedience.
Romans 5 “Therefore, since we have been justified through faith….justified by his blood”
