God's presence is all that matters.

Lukewarm living and claiming Christ's name simultaneously is utterly disgusting to God.

The point is not to completely understand God but to worship Him. Let the very fact that you cannot know Him fully lead you to praise Him for His infiniteness and grandeur.

I've never felt a need to really respond to someone else's writing.

Can you worship a God who isn't obligated to explain His actions to you? Could it be your arrogance that makes you think God owes you an explanation?

It's pride, plain and simple, that keeps me from giving God all the glory and keeping some of it for myself. It is a battle we all fight in some form or another, some of us daily or even hourly.

Christ can come back at any time so the one thing you want to have in your life is a focused prayer time.
