My friend Doug Wolter is a pastor at Oak Hill Baptist Church and is preaching through Colossians. He invited me down to preach on Colossians 3:22-4:1 yesterday, and I preached on what it means to do our work unto the Lord and for the good of others.
This also involved laying out a bit of a Christian doctrine of work from this text, since what the Bible has to say about our work is so often overlooked these days. You can listen to the message here.
