Martin Luther on Jesus

“I am certain that Jesus understood the difficulty inherent in the act of loving one's enemy. He never joined the ranks of those who talk glibly about the easiness of the moral life. He realized that every genuine expression of love grows out of a consistent and total surrender to God. So when Jesus said "love your enemy," he was not unmindful of its stringent qualities. Yet he meant every word of it. Our responsibility as Christians is to discover the meaning of this command and seek passionately to live it out in our daily lives.”

“Jesus recognized the need for blending opposites. He knew that his disciples would face a difficult and hostile world, where they would confront the recalcitrance of political officials and the intransigence of the protectors of the old order. He knew that they would meet cold and arrogant men whose hearts had been hardened by the long winter of traditionalism. … And he gave them a formula for action, "Be ye therefore as wise as serpents, and harmless as doves." … We must combine the toughness of the serpent with the softness of the dove, a tough mind and a tender heart.”
