65 Again, He was influenced by that threefold love, of which We spoke, during His public life: in long apostolic journeys; in the working of innumerable miracles, by which He summoned back the dead from the grave or granted health to all manner of sick persons; in enduring labors; in bearing fatigue, hunger and thirst; in the nightly watchings during which He prayed most lovingly to His Father; and finally, in His preaching and in setting forth and explaining His parables, in those particularly which deal with mercy--the lost drachma, the lost sheep, the prodigal son. By these indeed both by act and by word, as St. Gregory the Great notes, the Heart of God Itself is revealed: "Learn the Heart of God in the words of God, that you may long more ardently for things eternal."(59)
