And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons. – Genesis 3:7

When we find the first promise of our Lord’s coming, “in the volume of the Book,” we find that man’s covering was a failure. The guilty pair had gathered the leaves of the fig tree, and had made themselves aprons, for they knew that they were naked. This was the first fruit of that boasted tree of knowledge, and it is the principal one to this day. Their scant coverlet contented them for a little while; but when the voice of the Lord God was heard in the garden they confessed that their aprons were good for nothing; for Adam owned that he was afraid because he was naked, and that therefore he had hidden himself in the thick groves of the garden. It is easy to make a covering which pleases us for a season; but self-righteousness, presumption, pretended fidelity, and fancied natural excellence- all those things are like green fig-leaves, which shrivel up before long, lose their freshness, and are rather an exposure than a covering. It may be that my hearer has found his imaginary virtues failing him. It was when our first parents knew that they were naked that the Savior said, “Lo, I come.” My downcast hearer, if you are no longer in your own esteem as good as you used to be; if you can no longer hide the fact that you have broken God’s law, and deserve His wrath; if you no longer believe the devil’s lie that you shall suffer no penalty, but may even be the better for sin, then the Lord the Savior says to you, “Lo, I come.” To you, O naked sinner, shivering in your own shame, blushing scarlet with conviction- to you He comes. When you have nothing left of your own, He comes to be your robe of righteousness, wherein you may stand accepted with God. ~ C.H. Spurgeon
