I guess I need to give a little more info and direction for the devotional format I plan to follow. I figure it will change as I work through it, but my plan right now looks like this.
I will read through the book at the start. 1 Thessalonians is short enough that I should be able to get through it in a day. I will look for themes that the Lord is trying to communicate. I will then go back and start to work through the text at a slower pace. I will spend time meditating on the text, looking for the application the writer was going for and how can I apply it to my life. At some point. I imagine I will look at a Bible dictionary to get some background on Thessolonica, I may crack the Vines open if I need to understand a Greek word better. My guess is that I won't open those books until the middle of the month. At the end of the month, if there is something I am still confused about or want further clarification on, I will jump into a commentary. I imagine a lot of my time will be spent meditating on the text and how it applies to me, my family, or the youth group.
Hope that helps some.
