From Expository Thoughts on Luke, Bishop Ryle reflects on Lk. 9:10 ("On their return the apostles told [Jesus] all that they had done. And he took them and withdrew apart to a town called Bethsaida."):
Let us mark, secondly, the importance to Christians of occasional privacy and retirement. We are told, that when the apostles returned from their first ministerial work, our Lord 'took them and went aside privately into a desert place.' We cannot doubt that this was done with a deep meaning. It was meant to teach the great lesson that those who do public work for the souls of others, must be careful to make time for being alone with God.J. C. Ryle, Expository Thoughts on Luke, vol. 1 (Carlisle, PA: Banner of Truth Trust, 1986) 297.
The lesson is one which many Christians would do well to remember. Occasional retirment, self-inquiry, meditation, and secret communion with God, are absolutely essential to spiritual health. The man who neglects them is in great danger of a fall. To be always preaching, teaching, speaking, writing, and working public works, is, unquestionably, a sign of zeal. But it is not always a sign of zeal according to knowledge. it often leads to untoward consequences. We must take time occasionally for sitting down and calmly looking within, and examining how matters stand between our own selves and Christ. The omission of the practice is the true account of many a backsliding which shocks the Church, and gives occasion in the world to blaspheme.
