All this is to say that Christians often wander through life wondering what God is specifically telling then to do when a simple examination of whether or not they are violating His commandments will give them the answer. They worry over things like “where should I go” and “what should I do” when instead they should be looking at whether it is goes against the moral or sovereign will of God that is given to us in scripture. Like you said, “their own selfish desires” arise when they are looking for direction. But because their selfish desire is sinful, the answer is already in front of them, and of course they try blame a higher power when their “well-being is not like a river.”

Please note that I’m not taking an extreme view here and implying that God doesn’t sometimes tell people exactly what they should do. Rather that they should acknowledge that they were born with the capacity to sin and it is in their nature to be drawn toward their own desires. Therefore they should not act on feelings but instead analyze and look through the “eyeglass” that is the word of God.
