4 In your struggle against sin, you have not yet resisted to the point of shedding your blood. 5 And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says,
“My son, do not make light of the Lord’s discipline,
and do not lose heart when he rebukes you,
6 because the Lord disciplines the one he loves,
and he chastens everyone he accepts as his son.”[a]
7 Endure hardship as discipline; God is treating you as his children. For what children are not disciplined by their father? 8 If you are not disciplined—and everyone undergoes discipline—then you are not legitimate, not true sons and daughters at all. 9 Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of spirits and live! 10They disciplined us for a little while as they thought best; but God disciplines us for our good, in order that we may share in his holiness. 11 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.
12 Therefore, strengthen your feeble arms and weak knees. 13 “Make level paths for your feet,”[b] so that the lame may not be disabled, but rather healed.
Children need guidance (12:7-9)
The point of parenting is to teach our children how to make the best choices. Children need rules. They need limitations. They need boundaries. We love our children by not allowing them to hurt themselves. Verse 8 says that we are not legitimate if we have not undergone discipline. Verse 9 says that we learn to respect from discipline.
We need guidance (12:10-11)
We receive discipline and guidance because it is leading us to what is good. We will receive a share in his holiness. Discipline is never meant to be easy or pleasant. The short term is not the goal. We are in this for the long haul. Verse 11 tells us that we can know righteousness and peace because we have been trained for it.
We become good examples for others (12:12-13)
We are being trained for a purpose. We should “strengthen” our arms and knees to support others. When you lift something up, you use your arms and knees. As we are lifted up, we should lift up others! We undergo training and discipline to strengthen us to be strong for others!
