God's chastisement is love, but I don't think hell and wrath is love. It is judgement and eternal punishment. However, all through out scripture God does send out a warning, and sent his Son to die for the world. So he sent the warning, message, and an escape for any who would believe.
Scripture says that God is not slack concerning his promises. He is long suffering not willing that any should perish, but that all come to repentance.
Also scripture states that he takes no pleasure in the death of the wicked...and even instructs them to turn and live.
Ezekiel 33
Therefore, O thou son of man, speak unto the house of Israel; Thus ye speak, saying, If our transgressions and our sins
be upon us, and we pine away in them, how should we then live?
11Say unto them,
As I live, saith the Lord GOD, I have no pleasure in the death of the wicked; but that the wicked turn from his way and live: turn ye, turn ye from your evil ways; for why will ye die, O house of Israel?
