Psalm 95:7b-11 The Knowledge of God and Unbelief

So while in worship on Friday night of the Omaha conference I just got back from (I went with a 7 Thunders team from the house of prayer that included Kirk and my best friend Genevra...I loooved seeing her!) I stumbled upon a provoking passage:
"Today, if you will hear His voice; Do not harden your hearts, as in the rebellion. As in the day of trial in the wilderness; When your fathers tested Me; they tried Me, though they saw My work. For forty years I was grieved with that generation, And said, "It is a people who go astray in their hearts. And they do not know My ways." So I swore in My wrath, 'They shall not enter My rest."
Psalm 95:7b-11
Eeek. I don't even know why I'm blogging on it because I have no revelation on my heart whatsoever concerning it. I read Hebrews 3 and 4 that is dedicated to these very verses and got even more confused. The only thing I know is that the Lord is calling me into knowing His ways...and that I don't, and we don't, really know Him.
At the same time while reading this passage in worship Genevra was eating the dirt and God was speaking to her something equally sobering, and around the same theme. He was telling her that we so often say we want to know Him, but His heart is truly grieved because we don't want to know who He really is. In His perfect leadership, in His crazy zeal and fullness, In His love that costs us everything.
The knowledge of God and fighting unbelief are becoming two major highlight jump points inside of my soul. I am fully aware of my lack of belief and my dependence on God to actually believe He is who He says He is. It sounds simple but is so true. Because if we really believed that He is all the wonderful things that the Word that became Flesh says he is...well, I know I'd be living my life a bit differently. And I'd believe that His crazy leadership is way better than taking matters into my own hands. And I'd believe that He will provide for me. And that there is real abundant life. I think anyhow. I mean to a degree I believe these things. But I wonder how my life would transform if I walked just a little closer, or if I knew His ways. If while I was in the wilderness seasons I wouldn't harden my own heart. I wonder what it would look like if we all gave that a shot.
