Jesus started things. The rest of the N.T. authors continue that. Until I heard others talk about excluding Paul, it never occurred to me that one might see a conflict. I can understand why one might think this, but I got through it by never wavering in my belief that the bible is the word of God.
After decades of reading it, I've concluded that it never contradicts itself. I had to arrive here with the Lord's guidance...no one else could do this for me.
" …3if you truly call out to insight and lift your voice to understanding, 4
if you seek it like silver and search it out like hidden treasure, 5then you will discern the fear of the LORD and discover the knowledge of God.…" - Proverbs 2:3-5 Berean Study Bible
I include the O.T. A different covenant, but it's full of God's wisdom. From Genesis to Revelation, I love the book because it helps me in so many ways. Paul is a great part of it. God speaks to me through all of it.
