Hello there. This is Mark Bauerline with another conversation. Before we get to it, a word about one of our sponsors.

Would you like to spend more time in God's Word? Does your tight schedule prevent you from

sitting down with your Bible? Do you sometimes find the Bible confusing? The Word of the Lord

endures forever is a daily 15-minute verse-by-verse Bible study with the church, past, and present.

It's hosted by Lutheran Church Missouri Synod Pastor Will Whedon.
