God is not anger though He can be angry, God is not vengeance though He does avenge. These are attributes, love is essence. Therefore God is unchangeably love. In judgment He is love, in wrath He is love, in vengeance He is love – ‘love first, and last, and without end.’ Love is simply the strongest thing in the universe, the most awful, the most inexorable, (not to be moved by entreaty) while the most tender.
Thomas Allin. Christ Triumphant. 1878. Rpt. 9th ed. Canyon Country, CA : Concordant, n.d. 76 - 77.
Thanks to Beryl Spikings for pointing me to this quotation.
