Hebrews 12:11-13

111For the moment, all discipline seems not to be pleasant, but painful; yet to those who have been trained by it, afterward it yields the 2peaceful fruit of righteousness.

12Therefore, 34strengthen the hands that are weak and the knees that are feeble, 13and 5make straight paths for your feet, so that the limb which is impaired may not be dislocated, but rather 6be healed.
