This is in the Episcopalian prayer book:

Almighty God, we beseech thee to look with favor upon our land and people. All undeserving, thou hast made us great among the nations of the earth. Let us not forget that this place and this power have come of thee, and that we have them as a trust to use in thy service. Save us from pride and arrogance; make us quick to see the needs of those less fortunate than ourselves, and to be resolute in purpose to promote goodwill and fellowship among all men; through Jesus Christ our Lord.
