The Real Battle

One of the countless amazing truths revealed in the Bible is that humans are not our enemy. Ephesians 6:12 asserts We do not contend against flesh and blood, but against rulers, against authorities, against the powers of this dark world, against spiritual forces of evil in the heavenly realms.
When Jesus prayed from the Cross, "Father, forgive them, for they don't know what they are doing",  He was bringing this truth into focus. He knew that Judas, the Pharisees, and Roman soldiers were not his enemy. He knew that they had been deceived by the evil Prince of this World, Satan. They were victims--like we all have been, and to some degree still are. The "spiritual forces of evil" continue to use our human differences to deceive us into believing that those who are different from us are our enemies. Evil is indeed real. But those who practice it are deceived because it can never have a positive outcome. Evil is, by definition, destructive to both the perpetrator and the victim, but especially to the perpetrator. Jesus made it very clear to His followers that He was not a victim. "No man takes my life from me, I lay it down of my own accord." "I have overcome the world." He won the spiritual war because He was not overcome by fear or hatred. He loved to the end.
This is a very good way to understand life, even if you are an atheist. We war not against humans, but against aspects of our individual and collective personalities, false and destructive beliefs,  delusions, hatred of persons, greed, selfishness, avarice, malice, etc.  These are manifestations of our enemy. When we work to rid our own personalities of all that is not kind, faithful, and true; free, courageous and motivated by good will toward all, then we are fighting the right battles.
From the Christian perspective, we have Christ Himself, His very Holy Spirit, with us always to empower us on toward victory.
God please hasten the day when evil is eradicated from the new heavens and the new earth. And please keep on keeping my heart free from evil invasions; as You have designed my body to fight off the perpetual invasions of harmful organisms.
