You are partly correct.
After you outline Galatians, I’d love to hear your conclusions.
Before seminary, I started to outline books of the Bible, verse by verse, paragraph by paragraph.
Later, I had to do every book in the OT and NT.
It was a lot of work, but fruitful work.
Chapter 1Standard greeting in which Paul reminds the Galatians of his apostolic authority, an authority that comes directly from God. The assertion of this authority will be important to counter those who are teaching another gospel. He also repeats the gospel declaration that Jesus gave himself up to rescue us from our sins. Is there anything else that you would wish to add?
1 Paul, an apostle not from human beings nor through a human being but through Jesus Christ and God the Father who raised him from the dead, 2 and all the brothers who are with me, to the churches of Galatia: 3 grace to you and peace from God our Father and the Lord Jesus Christ, 4 who gave himself for our sins that he might rescue us from the present evil age in accord with the will of our God and Father, 5 to whom be glory forever and ever. Amen.
