Reader, can you find rest apart from the ark, Christ Jesus? Then consider that your religion may be in vain. Are you satisfied with anything short of a conscious knowledge of your union and interest in Christ? Then woe to you. If you profess to be a Christian while finding full satisfaction in worldly pleasures and pursuits, your profession is probably false. If your soul can stretch herself at rest and find the bed long enough and the blanket broad enough to cover it in the chambers of sin, then you are a hypocrite and far away from any proper thoughts of Christ or awareness of His preciousness.
But if, on the other hand, you feel that if you could indulge in sin without punishment, that would be a punishment itself, and that if you could have the whole world and live in it forever, it would be quite enough misery not to be separated from it, for your God—your God—is what your soul longs for, then be of good courage, you are a child of God. With all your sins and imperfections, take this for your comfort: If your soul has no rest in sin, you are not as the sinner is! If you are still crying after and craving after something better, Christ has not forgotten you, for you have not quite forgotten Him.
The believer cannot do without his Lord; words are inadequate to express his thoughts of Him. We cannot live on the sands of the wilderness—we want the manna that drops from heaven; the pitchers of self-confidence cannot produce for us a drop of moisture, but we drink of the rock that follows us, and that rock is Christ. When you feed on Him, your soul can sing, “He who satisfies me with good so that my youth is renewed like the eagle’s”;1 but if you don’t have Him, your wine cellar and well-stocked pantry can give you no sort of satisfaction: Learn to lament over them in the words of wisdom, “Vanity of vanities, all is vanity!”
