No single attribute can convey the nature of God’s relationship to man. Since justice is His nature, love, which would disregard the evil deeds of man, would contradict His nature. Because of His concern for man, His justice is tempered with mercy. Divine anger is not the antithesis of love, but its counterpart, a help to justice as demanded by true love.----------------------------/
The end [result] of sentimentality is the enfeeblement of truth and justice. It is divine anger that gives strength to God’s truth and justice. There are moments in history when anger alone can conquer evil. It is after mildness and kindness have failed that anger is proclaimed.
