Brother, not everything Paul says is for "infants in Christ". He addresses "spiritual people" in ways that are difficult for "infants in Christ" to understand.
Dear brothers and sisters, when I was with you I couldn’t talk to you as I would to spiritual people. I had to talk as though you belonged to this world or as though you were infants in Christ. I had to feed you with milk, not with solid food, because you weren’t ready for anything stronger. And you still aren’t ready, for you are still controlled by your sinful nature. You are jealous of one another and quarrel with each other. Doesn’t that prove you are controlled by your sinful nature? Aren’t you living like people of the world? When one of you says, “I am a follower of Paul,” and another says, “I follow Apollos,” aren’t you acting just like people of the world? (1 Corinthians 3:1-4 NLT)
Paul assumes the listener knows what he has said elsewhere and uses summary words like "the law" where he has already expanded on that word elsewhere. I will add in what he summed up as "the Law", because he assumed that the listener was a "spiritual person" and not an "infant in Christ".
But when you are directed by the Spirit, you are not under [the condemnation of] the law of Moses. (Galatians 5:18 NLT fixed)
The "spiritual person" listening knows that he left out the word "the condemnation of" above because he already said it below so that it would be understood without Paul needing to constantly repeat himself when speaking of "the law", as if he were only speaking to "infants in Christ".
If the old way, which brings condemnation, was glorious, how much more glorious is the new way, which makes us right with God! (2 Corinthians 3:9 NLT)
United in our hope for the soon return of Jesus, Jorge
