“but they have rebelled.” This verse, and many like it, highlight the fact that people have free will and can make the choice to serve God or not. God is not in control of what we do. God writes this verse with a tone of surprise and disgust. He had done so much for Israel and they had remained unthankful. Thankfulness comes from the heart and is something that we can control if we want to, which is why God can command us to be thankful (Col. 3:15).
