I have been crucified with Christ and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave Himself for me Gal 2:20 NIV
Jesus said it Himself on the cross, “it is finished”. His work of redemption was accomplished once and for all. Our “part” in salvation is to merely come into agreement with what he accomplished on the cross. It’s more a revelation, an unveiling of the settled truth of the cross than a decision of our will.
Jesus broke through the veil of our religious system by submitting to it on the cross. It wasn’t a requirement to assuage Papa’s wrath against us, it was to show forth the futility of our fear based religion and the triumph of His love.
He could have come down here and tried to correct our foolish religious ideas, but instead He submitted to them and through His demonstration of infinite love on the cross abolished the law of religion forever.
Then just to prove beyond all doubt that He had put an end to religion, he raised up from the grave on the third day. The resurrection set Him apart from every other great prophet or spiritual leader or teacher forever.
“For it was only through this wonderful grace that we believed in him. Nothing we did could ever earn this salvation, for it was the gracious gift from God that brought us to Christ! So no one will ever be able to boast, for salvation is never a reward for good works or human striving.”
