"He captured Agag, the Amalekite king, but completely destroyed everyone else. Saul and his men spared Agag's life and kept the best of the sheep and cattle, the fat calves and lambs - everything, in fact, that appealed to them. They destroyed only what was worthless or poor quality" (1 Samuel 15:8-9).
Saul, the king of Israel, was instructed by the LORD to defeat the Amalekites, taking no prisoners, and destroying all valuables, taking nothing for themselves. Saul thought he did a good enough job, because he destroyed almost everything. 90% is good for a grade on a test in high school, but when it comes to obeying God, nothing less than 100% is acceptable. To God, it wasn't good enough. Partial obedience isn't really obedience at all. It's an insulting attempt at trying to fool God into believing that we're doing His will.
If we think about it, it's easy to see the similarities between Saul and our own lives. Consider the distractions in your life. You know, those things that cause separation and conflict in your relationship with God. Identifying them isn't so much the hard part, it's how much of it you eliminate. How easy it is for us to convince ourselves that we're doing the right thing by eliminating most of the sinful habits we struggle with, or doing most of what He's called for us to do. After all, we're making progress. In our homes, we never try to get rid of most of the mice, or fumigate most of the termites. Almost just isn't quite good enough. We should apply the same standard in our own lives. What God says to do is exactly what we must do. Anything less just isn't good enough.
What has God called you to do that you haven't yet done? What distraction in your life is holding you back from 100% obedience. The kingdom of Israel was taken away from Saul because he wanted to obey on his own terms. Obedience is never on our terms. Obedience is a form of humility, submission, and yielding. Anything less...it's just not good enough.
