If God is not the author of confusion, what about the Tower of Babel?
This isn't a difficult issue at all. On one hand, God is not the author of confusion: "For God is not a God of confusion but of peace, as in all the churches of the saints," (1 Cor. 14:33). The context of this verse is dealing with the gift of tongues as were spoken in Christian churches in its early years. Foreigners would attend these churches and hear their own languages being spoken. There would often be interpretations of these tongues. Also, Christians would be over eager in their use of various tongues and this would often lead to confusion as people did not do things in order. Therefore, in the immediate verses prior to (1 Cor. 14:33), Paul had just given instruction on the proper use of the tongues in the church, a use which stated order and sequence. The goal was not to produce a confusion among the hearers so that they would not understand the gospel. Instead, it was to produce an orderly service of worship.
