Let us observe the manner in which this feeling grew to such strength as to give rise to a new line of conduct. It got entrance into _his heart_. It hovered about him in a somewhat loose form, before he took hold of it, and resolved to act upon it. It approached him in the same manner in which temptation approaches many a one, first presenting itself to the imagination and the feelings, trying to get hold of them, and then getting possession of the will, and turning the whole man in the desired direction. Like a skilful adversary who first attacks an outpost, apparently of little value, but when he has got it erects on it a battery by which he is able to conquer a nearer position, and thus gradually approaches, till at last the very citadel is in his hands,--so sin at first hovers about the outposts of the soul. Often it seems at first just to play with the imagination; one fancies this thing and the other, this sensual indulgence or that act of dishonesty; and then, having become familiar with it there, one admits it to the inner chambers of the soul, and ere long the lust bringeth forth sin. The lesson not to let sin play even with the imagination, but drive it thence the moment one becomes conscious of its presence, cannot be pressed too strongly. Have you ever studied the language of the Lord's Prayer?--"Lead us not _into_ temptation." You are being led into temptation whenever you are led to think, with interest and half longing, of any sinful indulgence. Wisdom demands of you that the moment you are conscious of such a feeling you resolutely exclaim, "Get thee behind me, Satan!" It is the tempter trying to establish a foothold in the outworks, meaning, when he has done so, to advance nearer and nearer to the citadel, till at last you shall find him in strong possession, and your soul entangled in the meshes of perdition.
The conclusion to which David came, under the influence of distrust, as to the best course for him to follow shows what opposite decisions may be arrived at, according to the point of view at which men take their stand. "There is nothing better for me than that I should escape speedily into the land of the Philistines." From a more correct point of view, nothing could have been worse. Had Moses thought of his prospects from the same position, he would have said, "There is nothing better for me than to remain the son of Pharaoh's daughter, and enjoy all the good things to which Providence has so remarkably called me;" but standing on the ground of faith, his conclusion was precisely the opposite. Looking abroad over the world with the eye of sense, the young man may say, "There is nothing better for me than that I should rejoice in my youth, and that my heart should cheer me in the days of my youth, and that I should walk in the ways of mine heart and in the sight of mine eyes." But the eye of faith sees ominous clouds and gathering storms in the distance, which show that there could be nothing worse.
