What part of loving others is it that we don't understand? God commands us to love Him and to love others. I was reading a post by Carl Tuttle called Your Brother Isn't Your Enemy. Sometimes we will have disagreements with others. Why is it that we shun others who don't believe the way we do or disagree with us on what I like to call "stupid shit"? You know, stuff like Politics, Doctrine, etc. Does it really matter? Carl ends his post with these words, and they are excellent words of advice.
When you are tempted to criticize and attack a brother or sister in Christ, remember “Your brother isn’t your enemy, even when he acts like it!”
