To a less dramatic extent, simply living one's life in the community while demonstrating the virtues of one's faith show that it's possible to be both "worldly" and connected to the Divine.

With all due respect, that is the crux of the biscuit, isn't it? I find no universal agreement that it is indeed possible to be both "worldly" and connected to the Divine. By contrast, there does seem to be some broad agreement among the world's spiritual traditions that removal from this world, in so much as such things are practicable, is at least a necessary precursor to realizing that Divine connection.

If realization of the Divine propels one into the world, to minister unto the world, to be a light unto the world, then it's not something about which an outsider can have a meaningful opinion. However, I don't think we can insist on active participation in this world being necessary or even desirable, at least from a spiritual perspective.
