"Discipline" - an unhelpful translation?

Here's a passage which I find really unhelpful when you're going through a hard time, but which shouldn't be...

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,
because the Lord disciplines the one he loves,
and he chastens everyone he accepts as his son.’

Endure hardship as discipline; God is treating you as his children. For what children are not disciplined by their father? If you are not disciplined – and everyone undergoes discipline – then you are not legitimate, not true sons and daughters at all. 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! They 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. 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.
Hebrews 12:5-11, NIV

So what? We're meant to endure hardship as discipline? Try telling that to the woman whose child has died – that it's God disciplining her! How's that a “word of encouragement”? It's stupid, pastorally insensitive, and just plain wrong. We don't live under the law. We don't believe in a God who gives us petty material rewards for obedience and punishments for disobedience. Maybe that's the way it worked in Leviticus, but not for the Christian.

There are two problems here. The first is the word “discipline” - most translations seem to use it in Hebrews 12, but I don't think it's warranted.

Discipline: the practice of training people to obey rules or a code of behaviour, using punishment to correct disobedience.
παιδεια: upbringing, training, instruction.

The Greek word which we translate as “discipline” doesn't quite mean that though. “Training” would be a better translation – it's the idea of an adult training a child. Sometimes that involves punishing disobedience - we suffer because we do things wrong. Sometimes, like with hard physical training, it's difficult and painful when we do it right as well. The word used for "discipline" here carries both ideas - it's the same word translated “training” in 2 Timothy 3:16. The passage isn't saying that all hardship is discipline. It's saying that God uses hardship to train us, like any kind of training can be hard, but we respect it and work with it.

The NIV translators generally did a great job – it's just about the best translation of the Bible into modern English. But they had a shocker when it got to Hebrews 12:7, and most other translations didn't do a lot better...

“Endure hardship as discipline – God is treating you as his children.” (NIV)
“It is for discipline that you have to endure. God is treating you as sons.” (ESV)
”Be patient when you are being corrected! This is how God treats his children.” (CEV)
”Endure what you suffer as being a father's punishment; your suffering shows that God is treating you as his children.” (Good News)
If you endure chastening, God deals with you as with sons;” (NJKV)

The NRSV is probably the most helpful of the major translations here, except that it still uses “discipline”; “Endure trials for the sake of discipline. God is treating you as children...”
I think Eugene Peterson pretty much nails the sense though in the Message:

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.

The idea is that we should endure difficulties and hardship because God uses them to train us. God is our Father. He hasn't let go of us; he isn't leaving us to the ravages of chance or punishing us for our own weakness. He knows what he is doing, and he is training us to trust him, even in and through the difficult times. Now that's a comfort, and an encouragement to keep going!

Christians and the OT Law

Here are 10 quick tips on how to apply and understand the Old Testament Law as Christians.

1. The Law isn't just commandments. The Jewish word usually translated "law" - Torah - actually refers to the first 5 books of the Bible. What we read as commandments are set within the context of story, and are inseparable from it.
2. The Law was always about how to respond to salvation. Just before the 10 Commandments are given comes the wonderful Exodus 19. The Law, for the people of Israel, was about how to respond to the fact that God had already saved them, and how to continue as God's saved people.
3. The Law was given to the nation of Israel - it was given in a specific time and context to a specific group of people to show them how to respond to God saving them from slavery in Egypt. It wasn't given to 21st century Gentile Christians living in the UK (or anywhere else). So it doesn't apply directly to us.
4. The Law was given in the knowledge it wouldn't be kept. Just after the commandments finish, in Deuteronomy 32, comes a wonderful song from Moses responding to the law. And in it, he recognises that the people won't keep the law and will need saving again. Jesus isn't therefore a Plan B, he is part 2 (or 3, or whatever) of Plan A. The Law shows us that we are incapable of keeping it, despite the best possible carrots and the worst possible sticks. The problem is the human heart.
5. Jesus is the perfect Law-keeper. But Jesus kept the Law perfectly. He did what we could not do.
6. Jesus embodies the character of God as revealed in the Law. He doesn't just fulfil the Law by not breaking it - he shows us more clearly the God who gave the Law.
7. Jesus is the answer to the problem posed by the Law. The problem the Law shows is that even if God rescues us, we still can't live up to it. Jesus solves that by rescuing us from our own inadequacy, from God's right anger against that inadequacy, and by giving us his Spirit to live in us and transform us.
8. The Law reveals the character of God our Father, especially in the importance of love - loving God and those around us, as well as showing us worked examples of what that love looks like in the culture of the time. We can therefore apply it to how we should respond to God's greater salvation in Jesus, but to do that takes work. There's a great outline of how to go about it in CJH Wright's book Old Testament Ethics for the People of God.
9. The Law leads us to God the Son, and shows us our need of his sin-bearing sacrifice.
10. The Law shows us our need for transformation by God the Holy Spirit. In New Testament thought, the Spirit replaces the Law. That is why there are so many parallels between Pentecost and Sinai.
