Jesus begins this section of His sermon by addressing those who are really hearing and taking to heart what He is saying, i.e., His true disciples. He contrasts with the strong conjunction, "But," alla in Greek, those upon whom the woes are pronounced and His true disciples. To them as the "blessed" ones He commands them to love their enemies. "They will be able to love their enemies, etc. A new life and a new power are in their hearts, those of the kingdom of God, vs. 20, and they will show their presence in the most distinctive and tangible way. The fruits of repentance which Jesus names are those which the world cannot achieve by any ethics it may invent or practice." - Lenski
