"For God is not the author of confusion, but of peace, as in all churches of the saints."
However, the premise that confusion is always the role of the adversary/accuser is as faulty as the avoidance of the context of that verse.
What we call confusion may result from wonder in the face of the unknown and unfathomable. It may be a necessary step on the road to peace that passes understanding. It may be part of the tension that is resolved in faith.
What the pastor was advertising was, "Show up here and we will hand you all the answers on a silver platter with 3-4 easy steps."
That does not seem to be the way of God through confusion to peace.
How unlike the way Jesus taught when he presented a conundrum and then challenged the hearers to go and think and pray about it.
There is no confusion in that or about that.
