Beautiful "atonement", beautiful.
Let us not think the "Law"- (following God's Word) to the letter, will save us or condemn us.
I Cor. 3:13-15, shows us, that God's children will recieve rewards for the good they have done, but lose rewards as well, for works that burn. But, v 15 shows, even if all a child's works burn, "but he himself shall be saved; yet so as by fire". Old KJV.
So, Salvation has nothing to do with works and we need to keep focused on the "Grace of God" that saves. For people cannot go thru 80 plus years of an average lifetime, without making some mistakes all the way thru.
God declares thru the Apostles, even after becoming saved, we still battle our "carnal nature)- (old nature). And Paul himself declares how he worked, to keep his body under subjection. So, even the greatest of the apostles was susceptable to falling to sin if is not constantly on guard.
And look at how Paul and Barnabus parted ways in Ministry, being unable to fully agree on all things, causing enough division, they had to seperate. (Acts).
From the greatest to the least of God's Children in relationship with God, we all still mess up regardless.
God Bless!!
