Well said; no disagreement here. Darryl Hart has written about the inherent 'tension' of being 'heirs of the world' (the 'already') and yet pilgrims on our way (the 'not yet')--holding these two at once certainly creates tension, and requires patience and endurance. Same with having a grand vision and yet being 'faithful in little,' perhaps?
I think 1 Cor. 7 is instructive for this time of tension--yes, "build great things," but do it "as though not." Yes, "whatever we do, do it unto the glory of God," which means--go big, do it excellently. But in all our doing, don't let those "big ends" become or eclipse our "chief and highest end" (WLC 1). "For the present form of the world is passing away." That probably goes without saying.
Either way, "thy kingdom come!"
