Hebrews 12:5-13

5And you have forgotten the exhortation that addresses you as sons:

7Endure suffering as discipline; God is treating you as sons. For what son is not disciplined by his father? 8If you do not experience discipline like everyone else, then you are illegitimate children and not true sons. 9Furthermore, we have all had earthly fathers who disciplined us, and we respected them. Should we not much more submit to the Father of our spirits and live?

10Our fathers disciplined us for a short time as they thought best, but God disciplines us for our good, so that we may share in His holiness. 11No discipline seems enjoyable at the time, but painful. Later on, however, it yields a harvest of righteousness and peace2 to those who have been trained by it.

12Therefore strengthen your limp hands and weak knees.3 13Make straight paths for your feet,4 so that the lame may not be disabled, but rather healed.
