Read Isaiah 6:1-7
Have you ever seen an image of a bird caught in an oil spill? Covered in thick black sludge, it can’t fly and it can’t float. If you watch a bird in that situation, you will see something tragic: its instinct is to clean itself. It uses its beak to pull at the sludge, but the oil doesn’t come off. Instead, the bird just ends up swallowing the poison. The harder it tries to clean itself, the sicker it gets. It is totally, utterly helpless.
We are exactly like that bird when it comes to our sin. We know we are stained. We feel the guilt of a lost temper, a secret pride, or a lie we told to cover our tracks. So, our instinct is to scrub. We try to wash away the guilt with the soap of “good works.” We tell ourselves, “If I just volunteer more, or act nicer, or get my act together, the stain will fade.”
But it doesn’t work. You cannot scrub away a spiritual problem with physical effort. Like the bird, we are helpless to remove the stain of our own sin.
In Isaiah 6, the prophet Isaiah experiences this reality firsthand. When he sees the Lord sitting on a throne, high and lifted up, he doesn’t start listing his good deeds. He sees the terrifying purity of a Holy God, and he immediately realizes he is filthy. He cries out, “Woe is me! For I am lost” (v. 5). In Hebrew, that word “lost” means “undone.” Isaiah is coming apart at the seams because he knows he cannot survive in the presence of such holiness, and he has no power to fix it.
But then, the King makes a move.
Isaiah doesn’t climb up to God; God comes down to him. A seraph flies to Isaiah with a burning coal from the altar—a coal representing the fire of judgment that has already fallen on a sacrifice. The angel touches Isaiah’s lips and says, “Your guilt is taken away, and your sin atoned for” (v. 7).
Isaiah didn’t have to scrub. The King provided the cleansing that the sinner could never earn.
So, if you feel dirty today, stop trying to clean yourself. You cannot wash away your sin, but Jesus can. He has already taken the fire of judgment on the Cross so that you could be made clean. Stop looking at the stain and start trusting the Savior who washes you white as snow.
