God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)
God's wrath is not the outworking of impersonal laws of retribution which are built into the structure of reality, but the response of a righteous God to man's adamant refusal to accept His love. The Greek word refers to anger which is passionate and vehement.
It is clear that obedience is intimately related to assurance; if we do not live and practice righteousness we have no reason to think that we are “born of God.”
