“Now no chastening seems to be joyful for the present, but grievous; nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been trained by it.” Hebrews 12:11.
“If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten? But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons. Further, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live? For they indeed for a few days chastened us as seemed best to them, but He for our profit, that we may be partakers of His holiness.” Hebrews 12:7-10.
“For we have been consumed by Your anger, and by Your wrath we are terrified. You have set our iniquities before You, our secret sins in the light of Your countenance. For all our days have passed away in Your wrath; we finish our years like a sigh. The days of our lives are seventy years; and if by reason of strength they are eighty years, yet their boast is only labor and sorrow; for it is soon cut off, and we fly away.” Psalm 90:7-10.
“And we know that all things work together for good to those who love God, to those who are the called according to His purpose. For whom He foreknew, He also predestined to be conformed to the image of His Son, that He might be the firstborn among many brethren. Moreover whom He predestined [to be conformed to the image of His Son], these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.” Romans 8:28-30.
