Matt Chandler preaches a bit like a young John Piper, IMO. He is the Lead Teaching Pastor at The Village Church in the Dallas-Fort Worth area (they have several satellite campuses). He became most famous after he was diagnosed with terminal cancer, from which he was recently given a clean bill of health. This sermon from 6/22 is entitled: "Grace Made Visible: The Generosity of God."
Chandler weaves several texts together to show God's grace to us. One notable point: Jesus made the trees from which his cross would be made; the saliva glands which caused spit to be hurled at himself. We serve a generous God and we ought to reflect His generosity.
