Jeremiah

Call unto me, and I will answer thee, and shew thee great and mighty things, which thou knowest not.

Seek ye the Lord while he may be found, call ye upon him while he is near:

And I will bring the third part through the fire, and will refine them as silver is refined, and will try them as gold is tried: they shall call on my name, and I will hear them: I will say, It is my people: and they shall say, The Lord is my God.
