‘He knew what was in man.’ The words describe our Lord in presence of a fact universally recognized—man's moral unsatisfactoriness. He looks steadily at man's first offer of service, at man's first enthusiasm, when ‘many believed in His name,’ and He discerns behind it a disqualifying cause; something which prevents Him from trusting man as he is, and from committing to him the great work of His kingdom. He sees sin in man and all that sin involves of moral failure, of refusal to endure, of spiritual blindness, of lawless self-assertion, of passion, of selfishness, of self-will. That there is in human nature this disqualifying taint of sin is, we may say, a fact universally recognized. It is the fact which in slow embittering experience has turned philanthropists into cynics and saddened the wisest. But to our Lord it was a fact present from the first. ‘He needed not that any should testify of man.’ He reckoned with sin to start with. Therefore He could not use mankind, as it offered itself, for His purposes. It needed a fresh start, a vital re-creation, to fit it for such high ends.
