Exodus 33:18-23
18 Then Moses said, "Now show me your glory." 19 And the LORD said, "I will cause all my goodness to pass in front of you, and I will proclaim my name, the LORD, in your presence. I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. 20 But," he said, "you cannot see my face, for no one may see me and live."
We are frequently convinced that we want to know everything of God. Sometimes we sort of demand this. This is a great example of how our desire for knowledge exceeds our wisdom. If we demand to know all of God, perhaps without knowing it, we are trying to “master” God. It is of course not possible to do this – but some may believe it is. Anything you have mastered, you have placed beneath you. God will not be mastered, indeed cannot be mastered.
To feel that we must master God is to be left a person who has no ability for wonder. With nothing bigger than ourselves – no ability or capacity for wonder, we'll have no chance for joy. Joy comes from what is larger than us. So, our demand to master God becomes our road to depression. Neitsche and others created such a fellowship of cheerlessness.
No, what we want is enough knowledge to believe – not only about God but about all of life. Enough knowledge to trust, and then live the adventure. In other words, this means we want mystery – our souls need mystery – and thus wonder. Our joy depends on it.
If one demands to know all of God, then the mystery is lost. Lose the mystery, lose the joy.
