It appears here that you believe that grace is the get-out-of-jail-free card of Monopoly. That is part of the false teaching that the Church came up with while resisting the Truth of
freedom from sin - not just punishment. You quote it quite well.
Grace is not unmerited favor, it is the
power of God that He favors us with. That is why when we are weak, the Holy Spirit in us - His grace - strengthens us, and all we need. God's Power. This power is not of ourselves, lest we boast, but from God.
His Grace, His Power is what was missing in the Law, the Old Covenant. That is why the New Covenant has better promises. Jesus died and was resurrected so that we could die to our old carnal nature, and walk in newness of life - walk in the Spirit.
One of the Jewish writing styles is called a parallelism. A truth repeated twice using another word or phrase. Part of it will be the same identifying it as a parallelism, but the other part will be different in the two, clarifying what is meant. Here are two. In the first one, the apostle confirms that grace is power. Not a get out of jail free card, unmerited favor that the Church has brainwashed us with. This is the number one deception in the Church - Satan redefining GRACE. It is the power of God that enables us to minister effectively toward salvation with Truth - the narrow road; and not ineffectively with seducing definitions - the wide path.
Acts 4:33
And with
great power the apostles gave witness to the resurrection of the Lord Jesus. And
great grace was upon them all.
1 Corinthians 1:7-8
eagerly waiting for
