[God] never condemns long prayers that are sincere. Let us not forget that our Lord sometimes spent long nights in prayer. We are told of one of these – we do not know how frequently they were (Luke 6:12). He would sometimes rise a “great while before day” and depart to a solitary place for prayer (Mark 1:35). The perfect Man spent more time in prayer than we do. It would seem an undoubted fact that with God's saints in all ages nights of prayer with God have been followed by days of power with men.
