Trust and Obey

You know, that song couldn't have been written the other way around. I have two reasons:

First: it would not have had an even rhythm, "trust and obey", as apposed to "obey and trust"

Second: trust bring obedience, not the other way around. It could have been called "Trust then Obey". Obedience is the evidence of trust. Trust is not the product of obedience.
