Hebrews 12:7-13

It is for discipline that you endure; God deals with you as with sons; for what son is there whom his father does not discipline? But if you are without discipline, of which all have become partakers, then you are illegitimate children and not sons. Furthermore, we had earthly fathers to discipline us, and we respected them; shall we not much rather be subject to the Father of spirits, and live? For they disciplined us for a short time as seemed best to them, but He disciplines us for our good, so that we may share His holiness. All discipline for the moment seems not to be joyful, but sorrowful; yet to those who have been trained by it, afterwards it yields the peaceful fruit of righteousness. Therefore, strengthen the hands that are weak and the knees that are feeble, and make straight paths for your feet, so that the limb which is lame may not be put out of joint, but rather be healed.
