Guidance: More About His Glory Than Our Security

While dejunking/organizing on Monday night, I listened to a couple audio chapters of Knowing God by J.I. Packer. It's a great book to re-read (or listen). I'm doing the exact same thing tonight - it's great! This is from the end of chapter 20:

Not merely does God will to guide us in the sense of showing us his way, that we may tread it; he wills also to guide us in the more fundamental sense of ensuring that, whatever happens, whatever mistakes we may make, we shall come safely home. Slippings and strayings there will be, no doubt, but the everlasting arms are beneath us; we shall be caught, rescued, restored. This is God's promise; this is how good he is. 
Thus it appears that the right context for discussing guidance is one of confidence in the God who will not let us ruin our souls. Our concern, therefore, in this discussion should be more for his glory than for our security - for that is already taken care of. And our self-distrust, while keeping us humble, must not cloud the joy with which we lean on "the Lord Protector" - our faithful covenant God. - J.I. Packer
