We know that there are many false teachings and that does anger us. Yet God states that is sweetness to him to see harmony in the church. That means we have to give up anger towards our brothers when we disagree. Jonah was ticked of at God when he did not strike down Ninevah. Jonah's anger was not that of God's who gives a chance to repent. I wold like to see some of the horrible hypocracy in the church struck down right now. But God has his own ways. If we are mature Christians, or should I say Christians in the right spirit, we should know how to deal with disagreements without trying to ridicule the other. Talking to myself here also. Sometimes it might be that we just want to fight , cloaking it in what we think is righteous anger. We do need to have righteous anger but we can not use it to bring down our own desire for judgement.
