Read Zechariah 3 today.

Zechariah 3:1-4 NLT[1] Then the angel showed me Jeshua the high priest standing before the angel of the LORD. The Accuser, Satan, was there at the angel’s right hand, making accusations against Jeshua. [2] And the LORD said to Satan, “I, the LORD, reject your accusations, Satan. Yes, the LORD, who has chosen Jerusalem, rebukes you. This man is like a burning stick that has been snatched from the fire.” [3] Jeshua’s clothing was filthy as he stood there before the angel. [4] So the angel said to the others standing there, “Take off his filthy clothes.” And turning to Jeshua he said, “See, I have taken away your sins, and now I am giving you these fine new clothes.”
As Jeshua, the high priest, stood before the angel of the LORD, accusations were being made against him. His filthy clothing was proof of his guilt. Yet the angel stopped the accuser from making accusations and instructed others to remove the filthy clothing and replace it with clean clothing.
Jeshua was cleansed, not by his own action, but by the angel of the LORD. We cannot take away our own sin. Only God can do that. And doing so is something God has chosen to do. Our part is to stand before God, taking ownership of our sin, and trusting God to remove it from us.
