That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of Life. – 1 John 1:1

We shall never see as much blessing as we might until the work of the Church becomes far more general than it is at present. 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…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. Spurgeon
