Chapter 1✅ Application: From the chapter firstly he’s making clear that We (you & I) should seek God’s approval not ppl validation or be a people pleaser. Coz we can’t be his (disciples-apostles if we’re to persuade men). Also to carefully check every message that it aligns with the Gospel of Christ we received whether it be even the very person that introduced it to you or anyone else even (spirits- angels) if they contradict the main message then they’re to be cursed (don’t follow it - listen to it). Considering how “bad” he was and his history but still called / chosen directly by God almighty shows that no matter how wretched one can be God could still use them. So we shouldn’t let our past/history discourage us in our calling for God knew us way before we were even born and has a great plan for us. And Knowing that he’s able to transform- And can use that “not so good past as a way of reaching people for they took it to be a great testimony that the very person who was out to destroy them is now in front of the line with them preaching the message he was trying to get rid of. (After encountering Christ we should spend ordained time with him to better understand/ prepare what he’s calling us to do or be) .
