The Patience of God is Part of his Character

Then the LORD passed in front of Moses and called out: “The LORD, the LORD God, is compassionate and gracious, slow to anger, abounding in loving devotion and faithfulness,

‘The LORD is slow to anger and abounding in loving devotion, forgiving iniquity and transgression. Yet He will by no means leave the guilty unpunished; He will visit the iniquity of the fathers upon their children to the third and fourth generation.’

But You, O Lord, are a compassionate and gracious God, slow to anger, abounding in loving devotion and faithfulness.
