What, you believe Jesus taught his disciples to kill each other in wars because that's how you say we should show love for each other. People amaze me that they think a protestant killing a protestant and a Catholic killing a Catholic is showing love for each other cause that's how they believe Christians show love for each other.
As for the motive when it comes to wars if you think it hasn't been about power and greed you go ahead and tell that to yourself.
Christians are not authorized to fight against their enemies. The apostle Paul wrote to fellow Christians: “If possible, as far as it depends on you, be peaceable with all men. Do not avenge yourselves.”—
Romans 12:18, 19.
Instead of sending his followers to war, Jesus told them: “Continue to love your enemies and to pray for those who persecute you, so that you may prove yourselves sons of your Father who is in the heavens.” (
Matthew 5:44, 45) Even when the nation in which they live goes to war, Christians should remain neutral, “no part of the world.” (
John 15:19) If God wants his worshippers in all nations to love their enemies and to remain separate from the world, how could he support either side of a violent conflict today?
“My Kingdom is no part of this world. If my Kingdom were part of this world, my attendants would have fought that I should not be handed over to the Jews. But as it is, my Kingdom is not from this source.”—John 18:36.
Jesus was the greatest man that ever lived on this planet, yet he tells us that the kingdom (Government) we are to be loyal to is that Messianic kingdom he is King of and we are not to fight and kill for that kingdom like people kill for their human government. The nations belong to Satan, fighting for a human government is fighting for Satan.
