Hebrews 12:10-11
For they indeed for a few days as seemed proper to themselves corrected us; but he for our own advantage, that we might be partakers of his holiness.

Beloved, be not amazed at the fiery trial among you which is to bring you to the test, as though something strange happened to you;
Revelation 3:19
As many as I love, I rebuke and correct: be zealous then, and repent.
