I mean that the reason God seems to act in ways that make no sense to us is that our perceptions are wrong. Our expectations are subtly twisted. We long for things that harm us and run from the things that grow and heal us. We think good is bad and bad is good. God acts rightly, but to us, it seems confusing. Or sometimes plain wrong.
While we can learn or study techniques for almost anything we might want to accomplish, real understanding is not the mere accumulation of knowledge. Understanding cannot be realized by listening or reading about the realization of others. It must be achieved firsthand via substantive, direct perception in the moment.
