Why do Christians dance and sing in their churches ?

Drink with alcohol and dance with snakes? Not what most Christians would consider as a Godly form of worship. Keep in mind there are different sects of Christianity, some have false teaching and false prophets. Most of the groups you see on TV are Word-of-Faith and Roman Catholicism. There are some others though from various denominations. If we find that someone is not teaching according to the Bible, then we should find another church to attend. Sometimes people start out with the right intentions, but then the devil sometimes gets a foothold in their lives. We should try not to condemn them as people, but we shouldn't compromise on the truth.
