“As we look around God’s creation, as we contemplate all that Christ has done for us (that great evangelical emphasis), as we recollect that the same God sustains us even in life’s darkest hours, we are talking about one and the same God doing all those things. It was St Thomas Acquinas who reminded us that theology leads not so much to understanding as to adoration. We need to recall that, in the end, perhaps it is worship at which evangelicalism is at its most authentic. As evangelicals contemplate all that God has done, the most authentic response is adoring God for what God is and what God has done.
We have a sense of dissatisfaction not with who God is, nor with the gospel, but with our grasp of this God,with our intellectual apprehension and the response we make to God. Recollecting (in its dual sense of remembering and picking up) the doctrine of the Trinity, in effect, allows evangelicalism to open its treasure chest, hold up its contents one by one, savour them, and realise that there are enormous riches there – riches that have been entrusted to us, that are there to sustain us in our mission and ministry.”
