1) Worship Philosophy: Why new contemporary songs in corporate worship and why we sing primarily to God instead of just about God.
2) Response to Elder led vs. Elder rule: Distinguishing what scripture really says about Elders and church polity and what has been man made (i.e. congregationalism). Specifically dispelling what congregationalists have deemed as "musts" when in reality after taking a closer look are not in scripture at all.
3) Review of the book Going Deep by Gordon MacDonald (I'm currently about half way through). A lot of good stuff so far but it will depend on where it heads in the end.
