Pray without ceasing. – 1 Thessalonians 5:17

And when He had sent them away, He departed into a mountain to pray. – Mark 6:46

Sir Thomas Abney had for many years practiced family prayer regularly; he was elected Lord Mayor of London, and on the night of his election he must be present at a banquet, but when the time came for him to call his family together in prayer, having no wish either to be a Pharisee or to give up his practice, he excused himself to the guests in this way: he said he had an important engagement with a very dear friend, and they must excuse him for a few minutes. It was most true, his dearest friend was the Lord Jesus, and family prayer was an important engagement; and so he withdrew for awhile to the family altar, and in that respect prayed without ceasing. We sometimes allow good things to interrupt our prayer, and thus make them evil. Mrs. Rowe observes in one of her letters that if the twelve apostles were preaching in the town where she lived and she could never hear them again, if it were her time for private devotion, she would not be bribed out of her closet by the hope of hearing them. I am not sure but what she might have taken another time for her private devotions, and so have enjoyed both privileges, but at the same time, supposing she must have lost the prayer and have only got the preaching in exchange, I agree with her, it would have been exchanging gold for silver. She would be more profited in praying than she would be in hearing, for praying is the end of preaching. Preaching is but the wheat-stalk, but praying is the golden grain itself, and he hath the best who gets it.~ C.H. Spurgeon
