When God disciplines his people under either Old or New Covenants, it is not simply an expression of righteous anger. It is not merely a case of giving people what they deserve. Reproof and discipline in this life are acts of love designed to produce repentance, not an early preview of the torments of hell — though that is what certainly awaits the unregenerate if God’s warnings are ignored. But we have a God who declares he is not willing that any should perish, and he behaves consistently with that statement.
I like to think that if more people understood this we might see more repentance.
