Invitation to Christ
That's hard to answer but maybe Abraham. The part where God tells him to leave his home and doesn't quite tell him where he's going. But also when he asks him to sacrifice his son. Abraham is my go to when I need to get my faith right, and that's most of the time lol.
I have a couple of favorite scriptures/stories but I do have a little running joke when it comes to the small part about the evil spirits in Acts 19. I hardly ever read Acts 19:15 how it's actually written. Usually, I have to stop and add a few words (can't say them here) to the quote and act out the evil spirit like Deebo or somebody from the hood is saying it. Lol Although I read it in jest, that scripture always reminds me of how important it is not to imitate but to have a personal relationship with the Lord... These spirits are out here bold, make sure you have the Holy Spirit yourself.
