Even His all-seeing eye can go no deeper into you than to your secret thoughts. Go you as deep as God goes, and you will be a wise man; go as deep and as often as He does, and then you will soon come to see eye to eye with God, not only about your own thoughts, but about His thoughts too, and about everything else. Till you begin to watch your own thoughts, and to watch them especially in their aims and their ends, you will have no idea what that moral and spiritual life is that all God's saints live; that life that Christ lived, and which He this night summons you all to enter henceforth upon. It is such a happy fact that it cannot be too often told, that in the things of the soul really and truly to know and feel the disease is to have already entered on the remedy. You will not feel, indeed, that you have entered on the remedy; but that does not much matter so long as you really have. And there is nothing more certain among all the certainties of divine things than that he who feels himself to be in death and hell with his heart so full of by-ends is all the time as far from death and hell as any one can be who is still on this side of heaven. When a man's whole will and desire is set on God, as is now and then the case, that man is perilously near a sudden and an abundant entrance into that life and that presence where his heart has for so long been. When a man is half mad with his own heart, as Thomas Shepard for one was, that stranger on the earth is at last within a step of that happy coast where all wishes end. Watch that man. Take a last look at that man. He will soon be taken out of your sight. Ere ever he is himself aware, he will be rapt up into that life where saints and angels seek not their own will, labour not for their own profit or promotion, listen not for their own praises, but find their blessedness, the half of which had not here been told them, in glorifying God and in enjoying Him for ever.
