But if you do not obey the Lord, and if you rebel against His commands, His hand will be against you, as it was against your ancestors. 1 Samuel 12:15 NIV Bible
Well, first of all, I don't obey the Lord, because I'm fearful that He's going to be against me. This passage is really from the Old Testament, where His people were supposed to follow only Him, as He commanded them. But, being rebellious people, they turned to false gods, and sacrificed their own children to these false gods. That's why the Lord was against them.
The thing is, I'm still a Rebellious Christian. I will do what I think is best, or what I want and put what God wants me to do on the back burner. Of course these things seem important to me at the time, but is anything really more important that following what to Lord wants us to do?
In particular, when I let my eating get sloppy, that usually means that I'm not so focused on what the Lord wants in my life. I recently ate a large plate of fried potatoes and sausage, thinking, "I always eat so healthy, overdoing it this time won't hurt!" Well, I was wrong! I was up all night with diarrhea! The Lord knew what was best for me, and what wasn't compatible with my body, but did I listen? No, I'm really sorry that I didn't take the time to prayerfully ask the Lord about eating all of that, the way that I do when I'm more focused on His will for me. What a faith lesson!
