Are we keen to do that? I think you are mistaken. Perhaps you think that anything that pertains to our humanity is evil?
I believe that we are. When the Lord talked about the old and the new wine, He was talking about the Jewish system and Christianity, the old and the new. If we borrow the forms of David's day and try to incorporate that into Christianity, that is really trying to have the new wine in old skins.
It isn't that our humanity is evil - as I've said before, nature is right in its place. Nature is God's ordering, it isn't evil. No, if we look at ourselves and try to assess why we can't offer anything of nature to God, we won't get very far. But, if we look at the humanity of the Lord Jesus - well, then we see exactly, precisely what God takes delight in, what is most acceptable to Him as an offering of sweet savour. The hymn writer says "Were the whole realm of nature mine / It would be an offering far too small". Those are the words of someone who has got a large appreciation of the Lord Jesus. All else has disappeared from his view and estimation. That is how we can expand in our capacity for worship, through occupation with Him. Occupation with self will have the opposite effect - whether I'm occupied with how much I can give to God of all my talents, or conversely, if I'm occupied with how insufficient and unable I am to offer anything of myself to God. Both are self-occupation, and there's no profit in that. If I'm occupied with nature, then I'm not occupied with Jesus. There's a time and a place for nature's claims, but that isn't in the assembly, or in worship.
Peter, James and John must've got a touch as to this on the mount of transfiguration. Peter was keen to build three tabernacles, putting Moses and Elias alongside the Lord, and he had to be adjusted. He had to learn, great men though Moses and Elias were, that, in the divine estimation, Christ stands alone. "*This* is my beloved Son: hear him. And suddenly having looked around, they no longer saw any one, but Jesus alone with themselves." (Mark 9:7-8). What a precious word we have here! "They no longer saw any one, but Jesus alone with themselves." To be alone with Jesus in their midst, the One whose "garments became shining, exceeding white as snow, such as fuller on earth could not whiten them." (Mark 9:3). A fuller would use lye to draw out the impurities from cloth to whiten it. There was nothing in the Lord Jesus that needed the fuller's lye. There were no imperfections there. The Holy Spirit could descend on Him as a dove. It's as we get a deeper appreciation of the perfections of the Christ, we lose more and more of our self-regard. We're drawn into a full realisation that everything for God's pleasure is bound up in that One. "Behold", He says, "I make all things new" (Revelation 21:5).
