The message of Grace is the gospel.
Man tried righteousness by works, that didn’t work out. Until Christ came and did all the work himself, now all you’ve got to do is believe in Jesus.
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them. Ephesians 2:8-10
Grace overshadows the law. Through Jesus, grace was brought to you and all you needed to do was to plug into it through faith and you immediately became righteous. It was that simple. Such an effortless and easy way.
No man can ever enter heaven by trying to obey the laws, because none will ever be justified or made righteous with that system. Rom. 3:20
People should quit trying to be righteous by works and believe in the finished work of Christ. That’s the only way to become righteous and enter heaven. Selah
