‘The trouble with many people today is that they have not found a God big enough for modern needs‘.
Bible paraphraser J B Philips wrote this in 1961. ‘While their experience of life has grown in a score of directions, and their mental horizons have been expanded to the point of bewilderment by world events and by scientific discoveries, their ideas of God have remained largely static.‘
He went on to describe the dangers of not letting your understanding of God grow along with everything else:
‘It is obviously impossible for an adult to worship the conception of God that exists in the mind of a child of Sunday School age, unless he is prepared to deny his own experience of life. If, by great effort of will, he does this, he will always be secretly afraid lest some new truth may expose the juvenility of his faith. And it will always be by such an effort that he either worships or serves a God who is really too small to command his adult loyalty and cooperation.‘
(J B Philips Your God is Too Small, (Collier/Macmillan 1961) p 7).
I found these references to J B Phillips in David Bradstreet and Steve Rabey’s enjoyable astronomical tour Star Struck (Zondervan 2016), p261.
