Hebrews 12:11-14

No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it. Therefore, strengthen your feeble arms and weak knees. “Make level paths for your feet,” so that the lame may not be disabled, but rather healed. Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord.
