Hebrews 12:9-13
9 Furthermore we have had fathers of our flesh which corrected us, and we gave them reverence: shall we not much rather be in subjection unto the Father of spirits, and live?
10 For they verily for a few days chastened us afterb their own pleasure; but he for our profit, that we might be partakers of his holiness.
11 Now no chastening for the present seemeth to be joyous, but grievous: nevertheless afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby.
12 Wherefore lift up the hands which hang down, and the feeble knees;
13 And make straightc paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed.
