"Who out there Fears God"

Isaiah 50:10

Who out there fears GOD,

actually listens to the voice of his servant?

For anyone out there who doesn't know where you're going,

anyone groping in the dark,

Here's what: Trust in GOD.

Lean on your God!

This is one of those "we must just trust" passages which is both bewildering and comforting.  It would be nice if God explained everything that he does to us so that we could understand it, but that is not the way that God works (probably because we cannot understand things he does because we are not God). Instead—and this is the comforting part—God calls us just to trust in him (while listening to the voice of the suffering servant, which is Jesus—see Is 53).

So from this passage we take several things:

1. We ought to fear God

2. We ought to listen to the voice of his servant

3. We ought to trust in God when we do not know where we are going

In other words: We must just trust in God.
