What does it mean for us as Christians to be united to Christ? Do we lose our personality in this union? Do we experience union on some mystical plane? We often let this subject hang in the realm of the esoteric, when it should be something that causes us joy and wonder. Robert Letham has recently published a highly acclaimed book Union with Christ with P&R Publishing. I wanted to see if Robert had a message series on this subject and I happened to find a 2009 sermon series by Letham on the same subject.
