O taste and see that the LORD is good: blessed is the man that trusteth in Him. – Psalm 34:8

There is something which every believer can do for his Lord. He must be able to tell of what he has tasted and handled of the Word of Life, and if he has not tasted and handled it, then he is not a child of God at all. The best teaching in the world is experimental; nothing wins upon men like personal witnessing, not merely teaching the doctrine as we find it in the Book, but as we have felt it in its living power upon our own hearts. When we begin to tell of its effect upon ourselves, it is wonderful what power there is upon others in that testimony. A person talks to me about a certain medicine, how it is compounded, what it looks like, how many drops must be taken at a dose, and so on. Well, I do not care to hear all that, and I soon forget it; but he tells me that for many months he was bed-ridden, he was in sore distress and in great pain, and like to die; and, looking at him as he stands before me in perfect health, I am delighted with the change, and he says that it was that medicine which restored him. If I am a sick man in the same state as he was, I say to him, “Give me the name and address, for I must try that medicine for myself.” I believe that the simple witness of converted boys and girls, converted lads and lasses, especially the witness of converted fathers and mothers and friends beloved, the witness that comes of the grey head that is backed up by years of godly living, has a wonderful power for the spread of the gospel, and we cannot expect that God will give us any very large blessing until the whole of us shall be at work for our Lord. We need not all climb up the pulpit stairs, but each one of us can proclaim Christ according to our ability, and according to the circumstances in which He has placed us. When we shall do that, then we may expect to see “greater things than these.” Days that shall make us laugh for very joy of heart, and well nigh make us dance like David did before the ark, will come when all the rank and file of the army, and even those who halt upon their crutches, shall march unanimously against the foe.~ C.H.
