That is just it, we can not please God. The moment we accept that is the moment we truly lose self.
It is only by his grace that He is saving a group of people to do with what He will do with them in the world to come.
As long as we feel we have some part or action in this grand plan of God's we miss the entire purpose.
The hard part for us as humans is we want to feel significant somehow and that our actions somehow justify our relationship with God. However God demands something even greater than that, which is why he gave us laws we could never fulfill.
It is this thinking that I can do this or that and be right with God, that makes God very jealous because he want to be the one to save us, he wants us to realize the Law is too much, otherwise we take His glory away and what he did through His son. It is really quite sad, you and I have such polar opposite ideas, because we both desire to represent God's love to each other.
We need to just sit back in awe, and pray for forgiveness for our arrogant assumptions, that he needs us to feel pleasure.
