In this you rejoice, though now for a little while you may have to suffer various trials… – 1 Peter 1:6

Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God. – 2 Corinthians 1:4

This heaviness is of essential use to a Christian, if he would do good to others. Ah! there are a great many Christian people that I was going to say I should like to see afflicted-but I will not say so much as that; I should like to see them heavy in spirit; if it were the Lord’s will that they should be bowed down greatly, I would not express a word of regret; for a little more sympathy would do them good; a little more power to sympathize would be a precious boon to them, and even if it were purchased by a short journey through a burning, fiery furnace, they might not rue the day afterwards in which they had been called to pass through the flame. There are none so tender as those who have been skinned themselves. Those who have been in the chamber of affliction know how to comfort those who are there. Do not believe that any man will become a physician unless he walks the hospitals; and I am sure that no one will become a divine, or become a comforter, unless he lies in the hospital as well as walks through it, and has to suffer himself. God cannot make ministers-and I speak with reverence of His Holy Name-He cannot make a Barnabas except in the fire. It is there, and there alone, that He can make His sons of consolation; He may make His sons of thunder anywhere; but His sons of consolation He must make in the fire, and there alone. Who shall speak to those whose hearts are broken, who shall bind up their wounds, but those whose hearts have been broken also, and whose wounds have long run with the sore of grief? “If need be,” then, “ye are in heaviness through manifold temptations.” …I must add it is but for a season. A little time, a few hours, a few days, a few months at most, it shall all have passed away; and then comes the “eternal weight of glory, wherein ye greatly rejoice.” ~ C.H. Spurgeon
