If you walk around with hatred and prejudice in your heart and mind all day, morally you’re just as much a killer as the one who pulls out the gun. That seems to be what Jesus is saying. The evil and genocide of World War II was the final result of decades of negative and paranoid thinking among good German Christians, Catholic and Lutheran. The tragic fascism of Nazi Germany was fomenting in people’s hearts long before a political leader came to catalyze their hate and resentment. Now it seems we are seeing the same in the United States.
Jesus tells us to not harbor hateful anger or call people names even in our hearts like “fool” or “worthless person” (Matthew 5:22). If we’re walking around all day thinking, “What an idiot he is,” we are already in the state of sin. Sin is more a state of separation and superiority than any concrete action—which is only the symptom. How we live in our hearts is our real truth.
.. Jesus insists that we love our enemies and pray for those who persecute us (Matthew 5:44). For Jesus, prayer seems to be a matter of waiting in love, returning to love, trusting that love is the unceasing stream of reality. Prayer isn’t primarily words; it’s an attitude, a stance, a state that precedes “saying” any individual prayers. That’s why Paul could say, “Pray unceasingly” (1 Thessalonians 5:17). If we think of prayer as requiring words, it is surely impossible to pray always.
