I. Let us then see in what way we may regard St. Paul's imprisonment as an arrangement and outcome of Divine love. Take, for instance, St. Paul in his own personal life. This period of imprisonment, of enforced rest and retirement, may have been absolutely necessary for him. St. Paul had spent many a long and busy year building up the spiritual life of others, founding churches, teaching converts, preaching, debating, struggling, suffering. His life had been one of intense spiritual, intellectual, bodily activity on behalf of others. But no one can be engaged in intense activity without wasting some of the spiritual life and force necessary for himself. Religious work, the most direct spiritual activity, visiting the sick, or preaching the gospel, or celebrating the sacraments, make a tremendous call upon our devotional powers and directly tend to lower our spiritual vitality, unless we seek abundant and frequent renewal thereof at the source of all spiritual vitality and life. Now God by this long imprisonment took St. Paul aside once again, as He had taken him aside twenty years before, amid the rocks of Sinai. God laid hold of him in his career of external business, as He laid hold of Moses in the court of Pharaoh, leading him into the wilderness of Midian for forty long years. God made St. Paul His prisoner that, having laboured for others, and having tended diligently their spiritual vineyard, he might now watch over and tend his own for a time. And the wondrous manner in which he profited by his imprisonment is manifest from this very Epistle to the Ephesians, in which he describes himself as God's prisoner--not, be it observed, the prisoner of the Jews, or of the Romans, or of Cæsar, but as the prisoner of God--dealing in the profoundest manner, as that Epistle does, with the greatest mysteries of the Christian faith. St. Paul had an opportunity during those four or five years, such as he never had before, of realising; digesting, and assimilating in all their fulness the doctrines he had so long proclaimed to others, and was thus enabled out of the depth of his own personal experience to preach what he felt and knew to be true, the only kind of teaching which will ever be worth anything.
