Hebrews 12:10-11

10For our earthly fathers disciplined us for only a short time as seemed best to them; but He disciplines us for our good, so that we may share His holiness.

11For the time being no discipline brings joy, but seems sad and painful; yet to those who have been trained by it, afterwards it yields the peaceful fruit of righteousness [right standing with God and a lifestyle and attitude that seeks conformity to God’s will and purpose].
