A few weeks a ago I had the privilege of preaching at CenterPoint Church, in Concord, NH. Their lead pastor, Dave Spencer, and I used to serve together in South Portland. It was great time catching up with him and his family, and I was deeply encouraged by the group of Jesus followers that had gathered to worship there in the capitol that morning.
I preached a sermon called "The Meal Jesus Gave Us" (nod to N.T. Wright). In it, I give an overview of what the Lord's Supper is all about, and spent some time explaining two key OT background passages: Jeremiah 31:31-34 and Isaiah 25:6-9. (Pretty hard to do in about 30 minutes!) I cannot tell you how faith-invigorating Isaiah 25 has been to me over the past few years and how fills my heart with expectant joy whenever I drink the cup and eat the bread. If you have a chance to listen, I hope you're encouraged by what you hear.
