40 years...

For the past year and a half Matt and I have been in a period of waiting and working and praying for God to do a very specific something, and so far nothing has changed. This last couple of weeks I have felt like I was at the very end of my rope as far as waiting was concerned. I was angry at God, not just alittle angry, I was ANGRY at God. I was sick of feeling like we were sincerely seeking His plan, trying everything we could, and He was holding out on us. I was at a very low place...
In a totally unrelated conversation a friend from work shared with me that she had read Duet. 9 and it had been very meaningful to her, so when I came to read my Bible, being angry at God, I could think of nothing else, so I turned to Deuteronomy.
Let me share something that hit home, something that I have known since my days in VBS and never really KNOOOWN...God let the people wonder in the desert for 40 YEARS!!!! God tested the people, and let them get hungry and provided their food, and kept their feet from swelling, and gave them water, and kept their clothes from tearing, and led them around the desert in search of a place that He knew the directions to, for 40 years. I was humbled. I realize that for a while I have been asking God, in my own way, why He has brought me out of Egypt to die in the desert. He wanted to know what was in the peoples heart, and He wanted the people to know what was in His. I am on the verge of rambling, read Duet. 6-9. Why is is that we have to learn the same lessons for centuries?
