Not the most compassionate or sensitive comment but that is really what God is saying. We tend to act on feeling. I like doing something so I am enthusiastic about it. I don't "feel" like doing something but I have to do it so I do it begrudgingly and half-heatedly, complaining along the way. No matter how we "feel", we need to be enthusiastic about it. God doesn't feel like hearing all of our moaning and complaining but He does listen and we are grateful for that.
Lord, help me to be motivated by what is right and not by how I "feel".
