7Endure hardship as discipline; God is treating you as sons. For what son is not disciplined by his father? 8If you are not disciplined (and everyone undergoes discipline), then you are illegitimate children and not true sons. 9Moreover, 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 our spirits and live! 10Our fathers disciplined us for a little while as they thought best; but God disciplines us for our good, that we may share in his holiness. 11No 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.
12Therefore, 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.
I'm kind of digging the paraphrase of that from "The Message"
My dear child, don't shrug off God's discipline,
but don't be crushed by it either.
It's the child he loves that he disciplines;
the child he embraces, he also corrects.
God is educating you; that's why you must never drop out. He's treating you as dear children. This trouble you're in isn't punishment; it's training, the normal experience of children.
Only irresponsible parents leave children to fend for themselves. Would you prefer an irresponsible God? We respect our own parents for training and not spoiling us, so why not embrace God's training so we can truly live? While we were children, our parents did what seemed best to them.
But God is doing what is best for us, training us to live God's holy best. At the time, discipline isn't much fun. It always feels like it's going against the grain. Later, of course, it pays off handsomely, for it's the well-trained who find themselves mature in their relationship with God.
