Context

“And yet—this is the other and equally important side of it—this Helper who will, in the long run, be satisfied with nothing less than absolute perfection, will also be delighted with the first feeble, stumbling effort you make tomorrow to do the simplest duty. As a great Christian writer (George MacDonald) pointed out, every father is pleased at the baby’s first attempt to walk: no father would be satisfied with anything less than a firm, free, manly walk in a grown-up son. In the same way, he said, ‘God is easy to please, but hard to satisfy.’ The practical upshot is this. On the one hand, God’s demand for perfection need not discourage you in the least in your present attempts to be good, or even in your present failures.” source
