Fullness and freedom - two aspects of Christian life that we all want to share. Paul wrote about them at length (and depth) in his letter to the Christians at Colossae, where certain new teachers were proclaiming that mere Christianity is not enough. There is, they suggested, a fuller experience, a greater liberation, than they had so far enjoyed.
But Paul was adamant: all Gods fullness is in Christ alone, and only through his complete work are we set free. These are the great objective truths of the faith that Dick Lucas highlights in his exposition, enabling us to see both the riches that are ours in Christ and the irrelevance - even blasphemy - of all would-be improvements on what God has done.
