A friend and I recently both prepared and gave short talks to each other with the purposes of encouraging one another and ultimately, to bring glory to God. Here’s my talk, which goes through the book of Job and looks at God’s sovereignty throughout it.
I’m no authority on this topic but I did grow and learn quite a bit through preparation and delivery. It was/is a simple attempt to propel God’s name far above all else.
The notes I used for preparation/delivery are available as well.
