Zechariah 13:9

And I will bring the third part through the fire, the test of affliction and persecution as it soon came to the first congregation, and will refine them as silver is refined and will try them as gold is tried, Cf 1 Peter 1:6. They shall call on My name, and I will hear them, graciously giving them the attention which assured them of His certain assistance; I will say, It is My people, and they shall say, The Lord is my God. This has ever been the relationship obtaining between the God of the covenant and His Church on earth, and this intimate communion is one of the miracles of the Church till the end of time. Cf John 14:23.
