thus? Surely, the command teacheth us our duty, the promise our weakness and insufficiency to perform that duty. The command finds us work; the promise finds us strength: the command is to keep us from being idle; the promise to keep us from being discouraged. Well, let us imitate God, and, as He couples a command and a promise, so let us couple a resolution and a petition. As God seconds and backs His command with His promise, so let us second and back our promises with our prayers; the one in sense of our duty, the other in sense of our weakness; by the one, to bring our hearts up to God: by the other, to bring God down to our hearts: resolve and petition, promise and pray, and the Lord "prepare your heart to pray, and cause His ear to hear." _Secondly_, Since God only must uphold your desires, walk continually as in His presence; stability is only to be found in the presence of God; so far we live an unchangeable life, as we walk and live in the presence of an unchangeable God. The saints in Heaven know no vicissitudes, or changes in their holy frame and temper of spirit, because they are perfected in the beholding of His face; "with whom is no variableness, nor shadow of changing:" and so far as the saints on earth can keep God in their presence so far the presence of God will keep them. "I have set the Lord always before me; and because He is at my right hand, therefore I shall not be moved," sang David of himself literally, and in the person of Christ typically: the privilege was made good to both, so far as either made good the duty. David, according to his degree, and proportion of grace, set God before him, placed Him on his right hand; and so long as he could keep God's presence, the presence of God kept him; it kept him from sin, "I have kept myself from mine iniquity." How so? Why, "I was upright before Him," in the former part of the same verse. So long as he walked before God, in God's presence; so long he walked upright, and kept himself from his iniquity; or rather God's presence kept him: and, as it kept him from sin, so it kept him from fear also; "tho' I walk through the valley of the shadow of death, I will not fear." Mark what he saith, though he walk, not step; and walk through, not step across; and through, not a dark entry, or a churchyard in the night-time, but a valley, a large, long, vast place; how many miles long I know not; and this not a valley of darkness only, but of death, where he should see nothing but visions of death, and not bare death, but the shadow of death: the shadow is the dark part of the thing; so that the shadow of death, is the darkest side of death; death in its most hideous and horrid representations; and yet behold, when he comes out at the farther end, and a man would have thought to have found him all in a cold sweat, his hair standing upright, his eyes set in his head, and the man beside himself. Behold, I say, he doth not so much as
