Thought from Today's Old Testament Passage:
"If I justify myself, mine own mouth shall condemn me: if I say, I am perfect, it shall also prove me perverse." Job ix. 20.
Suppose now for a moment that a command is issued to the beasts of the forest that they should become sheep. It is quite in vain for the bear to come forward and plead that he was not so venomous a creature as the serpent; equally absurd would it be for the wolf to say that though stealthy and cunning, and gaunt, and grim, yet he was not so great a grumbler nor so ugly a creature as the bear; and the lion might plead that he had not the craftiness of the fox.
"It is true," saith he, "I wet my tongue in blood, but then l have some virtues which may commend me, and which, in fact, have made me king of beasts." What would this argument avail? The indictment is that these animals are not sheep; their plea against the indictment is that they are no less like sheep than other creatures, and that some of them have more gentleness and more docility than others of their kind. The plea would never stand. Or use another picture. If in the courts of justice, a thief, when called up, should argue, "Well, I am not so great a thief as some; … and if there be one conviction in the book against me, there are some that have a dozen convictions against them." No magistrate would acquit a man on such an excuse as that, because it would be tantamount to his admission of a degree of guilt, though he might try to excuse himself because he had not reached a higher degree.
It is so with you, sinner. You have sinned. Another man's sins cannot excuse you; you must stand upon your own feet. At the day of judgment you must yourself make a personal appearance and it will not be what another man has done that will condemn, or acquit you, but your own personal guilt. Take heed, then, take heed, sinner; for it will not avail thee that there are others blacker than thyself. If there be but a spot upon thee thou art lost; if there be but one sin unwashed by Jesus' blood, thy portion must be with the tormentors. A holy God cannot look even upon the least degree of iniquity. (C. H. Spurgeon, Treasury of the Old Testament, Vol. 2, (Grand Rapids, MI: Zondervan, 1962), p. 205)
