“’But love ye your enemies, and do good, and lend, hoping for nothing again; and your reward shall be great, and ye shall be the children of the Highest; for He is kind unto the unthankful and to the evil. Be ye therefore merciful as your Father also is merciful‘ (Luke 6:35-36).
These are the great heights to which Christ desires to raise men! This is teaching unheard-of before His coming! This is the glory of man’s dignity, undreamed-of by the greatest sages in history! And this is God’s love for mankind, that dissolves the whole heart of man into one great flood of tears.
‘Love your enemies.‘ He does not say: ‘Do not render evil for evil’, for this is a small thing; it is only endurance. Neither does He say: ‘Love those who love you’, for this is passive love; but He says: ‘Love your enemies‘; do not just tolerate them, and do not be passive, but love them. Love is an active virtue.” (St Nikolai Velimirovic, Homilies, p. 194-195)
