Jesus reveals what it is that, in the sphere of redemption, supremely rejoices his Father’s heart. It is not an elder brother who toils incessantly for the father, but a younger brother who lets the father do everything for him. It is not an elder brother who always wants to be the giver, but a younger brother who is always willing to be the receiver…
God is so wealthy that his chief delight is to give… It is a grief to the heart of God when we try to provide things for him. He is so very, very rich. It gives him true joy when we just let him give and give again to us. It is a grief to him, too, when we try to do things for him, for he is so very, very able. He longs that we will just let him do and do and do. He wants to be the Giver eternally, and he wants to be the Doer eternally. If only we saw how rich and how great he is, we would leave all the giving and all the doing to him.

Where does Jesus telling us to go and do things fit it then. Works prepared for us to DO? Or that we’re one spirit with him and we don’t separate what God has joined, and saying it’s God not us separates us. It’s us and God in my theology. We toil, God energises as Paul says in Phil 2:12-13.
