Why the church fears and trembles

Hear St. Jeremiah:

Thus says the LORD who made the earth… I will cleanse them from all the guilt of their sin against me, and I will forgive all the guilt of their sin and rebellion against me. And this city shall be to me a name of joy, a praise and a glory before all the nations of the earth who shall hear of all the good that I do for them. They shall fear and tremble because of all the good and all the prosperity I provide for it.

Hear St. Peter:

And if you call on him as Father who judges impartially according to each one’s deeds, conduct yourselves with fear throughout the time of your exile, knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot.
