God is a good, loving and all-wise God, so following his will is far better for us than following our own will. And following God’s will for our lives is better than just going with the flow, bobbing around like a cork in the ocean. And what we really want to avoid is coming to the end of our lives with a whole bunch of regret. We don’t want to be a person who says, “If only I had been following God, I would have made a different choice back there, and things would have been much different. And I wouldn’t have the horrible regrets that I have today.”
So it would be a good thing to know God’s Will, God’s direction, for our lives.
