Jeremiah 13:23 - Homiletics

The Ethiopian's skin and the leopard's spots.

I. SIN BECOMES INHERENT IN THE NATURE OF MEN . The black of the Ethiopian's skin and the spots of the leopard are natural. Sin is , of course, originally unnatural. Yet it is so engrafted into the very life of men that it becomes part of their nature.

1. Men inherit tendencies to evil; e . g . the child of the drunkard is likely to feel strong temptation to intemperance, etc. We are not to blame for what we inherit; but we do suffer through it. The degraded moral nature is a fact, and one for which the possessor of it suffers, although he will not be responsible for it, nor punished simply for having it, but only for the way in which, with his free-will, he yields to it, and, on his own account, makes it still more corrupt.

2. Men habituate themselves to sin. Habit is second nature. The sin which is willfully chosen becomes a tyrannous habit. We are coloring our very being by the tone of our thoughts and actions. What we do today, that we will be to-morrow. We are the result of our own past deeds. He who speaks or acts a lie becomes a liar; he who indulges in impurity becomes an unclean being; he who follows selfish impulses becomes a creature of selfishness. Thus every man is building up a habitation for his soul by his own deeds. What shall this house be? A temple of divinity? a palace of pure delights? a charnel-house of corruption? or a prison of gloom?

II. THIS INHERENT CONDITION OF SIN MAKES IT IMPOSSIBLE FOR ANY MAN TO IRRADICATE IT .

1. Self-reformation is impossible . Sin is not a mere defilement to be washed off. It is ingrained. It is in the blood, in the life, in the nature. Action is according to character. If the character is corrupt, so must be the action. It is true we are free to do as we will, but so long as our nature is corrupt we shall will to do evil, because the will is part of the nature. But apart from the vexed question of the freedom of the will, every man is conscious of the difficulty of overcoming opposing habits, even when his will is roused against them. When he would do good evil is present with him, and this evil is so strong that it can only be regarded as a law of (corrupted) nature ( Romans 7:21-23 ).

2. Perfect reformation must be sought from God . This must be regeneration ( John 3:3 ). Man can do much with himself, but only God can "create" in him" a clean heart" and make him" a new creature." Therefore, to be born again, we must be born "from above." Regeneration must be the work of the Spirit, which is the brooding source of all life. But this is possible for all ( Matthew 19:26 ). The impossibility for self-reformation should not leave us in sullen indifference, but should rouse us to seek the one sure means of renewal in crucifixion of the old life and spiritual resurrection to a new life, through yielding ourselves up to the influence of the grace of God in Christ Jesus.
