I will remove the sin of this land in a single day

Zechariah 3:1-10

The Lord, who has chosen Jerusalem, rebuke you! Is not this man a burning stick snatched from the fire?”

Now Joshua was dressed in filthy clothes as he stood before the angel. The angel said to those who were standing before him, “Take off his filthy clothes.” hen he said to Joshua, “See, I have taken away your sin, and I will put fine garments on you.” 

The angel of the Lord gave this charge to Joshua:  “This is what the Lord Almighty says: ‘If you will walk in obedience to me and keep my requirements, then you will govern my house and have charge of my courts, and I will give you a place among these standing here.

I am going to bring my servant, the Branch. See, the stone I have set in front of Joshua! There are seven eyes on that one stone, and I will engrave an inscription on it,’ says the Lord Almighty, ‘and I will remove the sin of this land in a single day.

Joshua, the high priest, stands before God representing the people, as Satan levels his charges against them. Joshua's filthy clothes are sin-stained. But God's set purpose is to restore and renew his people. He issues clean clothes to fit them for his presence, and a 'solemn charge'. As a token of good things to come God speaks of his servant, the Branch to come to God speaks of his servant, the Branch from the family of David who will usher in a day of universal peace and prosperity (the meaning of the vine and fig-tree symbol.)

Why?

There is the symbol of Satan and Joshua represents the sins and his people, Israelites. Even his people were defiled by the sins but the Lord will remove their sins through his branch, Jesus Christ. 

Jesus Christ removes our sin in a single day if anyone trusts in Him.

Jesus Christ is the stone, it is the cornerstone of our salvation.

How?

Before our born, God has arranged the salvation plan for all of us.
