Charles Spurgeon Commentary Zechariah 8:3

"Thus saith Jehovah: I am returned unto Zion, and will dwell in the midst of Jerusalem: and Jerusalem shall be called The city of truth; and the mountain of Jehovah of hosts, The holy mountain." — Zechariah 8:3 (ASV)

The first coming or the return of God to a church, or to an individual heart, always promotes holiness; so, unless your piety is daily growing, do not imagine that God is in the midst of you; for, wherever the Lord comes, he comes as a refiner and purifier. You will never find Jesus come except as John the Baptist pictured him to the Pharisees and Sadducees of his day: whose fan is in his hand, and he will throughly purge his floor. The coming of Christ into any soul, or into any church, is the death of sin and the birth of holiness.
