Thomas Manton, Works, 19:15:
It is most comfortable to observe how Christ upon the cross calleth God “Father.” He felt him a judge, and believeth him a father. The special work of faith in afflictions is to maintain the comfort of adoption: Heb. 12:5, “Ye have forgotten the exhortation that speaketh unto you as unto children, My son, despise not thou the chastening of the Lord.” Those that are under chastening may be sons. God doth not always put on the person of a judge when he taketh the rod in his hand; the change of your condition doth not alter, nor make void your interest. God is the God of the valleys as well as the God of the hills. Christ was now, as a man, forsaken and rejected of God, left to the assaults of Satan and scorns of men; and yet in the height of his pains and passion he retaineth his confidence: “Father, forgive them.” The whole world is not worth the comfort that is wrapped up in that one word, “Father.” It is a great folly in the children of God to question his love merely because of the greatness of their afflictions. We presently cry out, as Job, chap. 30:21, “Thou art become cruel to me; with thy strong hand thou opposest thyself against me;” that he hath put off all fatherly affection, because we judge of the cross according to the sense of our own flesh. And therefore, merely to question God’s love because of afflictions is folly. Rather we may conclude the contrary of the two. Bastards are left to a looser discipline than sons; the bramble of the wilderness is suffered to grow and spread when the vine is cut, and pruned, and pared; the stones that are to be set in the building are most hewed and squared, others lie neglected in the quarry and are left to their own roughness. Multiplied afflictions are a sign God hath a care of you; he will not suffer you to run wild. And therefore, in defiance of the cross, learn to call God Father; look through the cloud of the present dispensation to the love of God towards you.
