We know that our old self [our human nature without the Holy Spirit] was nailed to the cross with Him, in order that our body of sin might be done away with, so that we would no longer be slaves to sin.

But by God’s grace I am what I am, and His grace toward me was not ineffective. However, I worked more than any of them, yet not I, but God’s grace that was with me.

But if the ministry that produced death -- carved in letters on stone tablets -- came with glory, so that the Israelites could not keep their eyes fixed on the face of Moses because of the glory of his face (a glory which was made ineffective),

For if what was made ineffective came with glory, how much more has what remains come in glory!

Indeed, because it was weak and ineffective, the former commandment has been annulled,

For if you possess these qualities, and if they continue to increase among you, they will keep you from being ineffective and unproductive in attaining a full knowledge of our Lord Jesus, the Messiah.
