For He is not a God of the dead, but of the living: for all live unto Him. – Luke 20:38

If you have been quickened by the Spirit of God, your prayers are living prayers. Oh, the many dead prayers that are heard at the bedside; so many good words rushed through at a canter! He that is alive unto God asks for what he wants, and believes that he shall have it, and he gets it. That is living prayer. Beware of dead prayers; they are a mockery to the Most High. I do not think that a living man can always pray by clockwork, at such a time and such a time. It would be something like the minister’s sermon which he “got up” beforehand, and upon which he wrote in the margin “weep here,” “here you must show great emotion.” Of course that was all rubbish; it cannot be done to order. You cannot resolve to “groan at one o’clock, and weep at three o’clock.” Life will not be bound like that… Why, sometimes we can pray, and prevail, and come off conquerors; and at another time, we can only bow at the throne, and groan out, “Lord, help me; I cannot pray; the springs seem to be all sealed.” That is the result of life. Living things change… Yes, life is a strange thing; and if you have the life of God in your soul, you will undergo many changes, and not always be what you want to be….If we are alive unto God, every part of our worship should be living. What a deal of dead worship there is! That is not worship which consists in doing as Hodge did, when he said, “I like Sunday, for then I can go to church, and put my legs up, and think of nothing at all.” That is all the worship a great many render to God, just getting to a place of worship, and there sitting still, and thinking of nothing at all. But if you are a living child of God, you cannot do that. If, sometimes, through the infirmity of the flesh, you fall into that state of slumber, you loathe yourselves for it, but you rouse yourself up, and say, “I must worship my God; I must sing, I must praise God. I must draw near to Him in prayer.” ~ C.H. Spurgeon
