A Prayer to Begin the Day from the Scottish Prayer Book

O Lord God Almighty, eternal, immortal, invisible, the mysteries of whose being are unsearchable: Accept, we beseech thee, our praises for the revelation which thou hast made of thyself, Father, Son, and Holy Ghost, three persons, and one God; and mercifully grant that ever holding fast this faith we may magnify thy glorious name; who livest and reignest, one God, world without end.
