Modern society has often painted Jesus as a very "soft," even effeminate persona. It is certainly true that Jesus teaches us to be followers of peace and to turn the other cheek when we are reviled or insulted (Matthew 5:9, 38-39). However, being a peacemaker is not necessarily the same as being a pacifist. Keep in mind that this is the same Jesus who specifically instructed His followers to buy a sword ( Luke 22:36). In one of His parables, He portrays Himself as a landowner who imposes the death penalty on an unjust servant ( Luke 19:12-27). When He encountered a Roman military leader (Matthew 8:5-10), Jesus did not rebuke him in the least for his military occupation. Instead, He commends the soldier for his great faith, a faith so strong and pure that it put all of Israel to shame. In all of these areas, Jesus' teachings would be considered quite conservative by modern terms.
