Hebrews 2:10

In bringing many sons to glory, it was fitting that God, for whom and through whom everything exists, should make the author of their salvation perfect through suffering.

"There are many who are ready to tell us confidently what would and what would not be worthy of God; but in fact the only way to discover what is a worthy thing for God to do is to consider what God has actually done. The person who says, 'I could not have a high opinion of a God who would (or would not) do this or that,' is not adding anything to our knowledge of God; he is simply telling us something about himself. We may be sure that all that God does is worthy of himself, but here [the author of Hebrews] singles out one of God's actions and tells us that it was a fitting thing for him to do. And what was that? It was making Jesus, through his sufferings, perfectly qualified to be the Saviour of his people. It is in the passion [the death] of our Lord that we see the very heart of God laid bare; nowhere is God more fully or more worthily revealed as God than when we see him 'in Christ reconciling the world to himself' (2 Cor. 5:19)." - The Epistle to the Hebrews, F.F. Bruce, p. 80
