What a few thousand years of Israel’s efforts could not accomplish, the Lamb of God did with one single act. Christ succeeded at what that whole culture with all its wanderings, buildings, feasts and sacrifices was their utter failure to effectually deal with sin. If they had succeeded they would not have had to repeat them. But Christ said “Father if there be another way”? With no answer, Christ went to the cross and paid for all the sin of the world past present and future, in one fell swoop. He then offered a guilt free conscience with the right doing of faith in Him on all who would believe in Him, past present and future. As scripture says “whoever sins has neither seen Him or knows Him” because they have not learned to accept that fact that the power of sin was grounded out at the cross. Every negative feeling, act and all the consequences and ill effects of sins were defused there to clear your conscience for those who receive forgiveness. This is why Christ at the cross is the one saving act for humanity. He bridged the gap for humanity to God the Father, hence Paul pleaded “be ye reconciled to the Father. For He made Him who knew no sin to become oue sin, for us to become His righteousness to access the Father. And so He did. So we echo His words from the cross, “It is finished”.
The superfluous move of the Holy Spirit is not bound by law. Laws are for the lawless. The law of the Spirit of the life that is in Christ Jesus has set me free from the law of sin and death. The internal dwelling of the Holy Spirit in a believer supersedes and expires the need for any external motivators or controllers. The law is for the lawless and son neglegent (1 Tim )
Titus 1.15 To the pure all things are pure, but to those who are defiled and unbelieving nothing is pure; but even their mind and conscience are defiled.
