Luke 6:35 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.
Christians who critically judge others have a hard time embracing this Scripture. Man’s judgment opposes loving your enemies. Judgment carries a view of separation, superiority, and competition against the enemy. Our Heavenly Father is in the business of reconciliation, not separation. Jesus went to the cross to remove the barrier of separation between us and The Father. The veil in the Temple was ripped when Jesus died on the cross. That symbolic barrier of separation was eliminated. An enemy is one who opposes you, especially with hatred. Hate is "a feeling of dislike so strong that it demands action". This emotion evokes an action to oppose. Kindness causes hatred to dissipate. There is much hatred in the world today. The U.S. has many enemies around the world. Why? By invoking our will against others, hatred ensues. Who is to say that we have the right to invade other countries? What man can adequately define "our national interest’? Only the God of Heaven and Earth can righteously define "national interests".
Why do people become enemies? Often, the source of this hatred is competition. The competition may be for money, power, natural resources, or simply pride (ego). People get distracted by competition. There is an underlying assumption of scarcity that drives competition. Competition is divisive in nature by separating the conqueror from the conquered, the elite from the average, and the strong from the weak. Jesus saw no need to compete or to conquer. He came to reconcile a divided world. The best way to kill your enemy is with kindness, a method of conversion rather than destruction.
The word kind in Scripture is also translated as "easy": Matthew 11:30 For my yoke [is] easy, and my burden is light. Kindness will promote a lighter burden!
