To know — By loving, holy faith, thee the only true God — The only cause and end of all things; not excluding the Son and the Holy Ghost, no more than the Father is excluded from being Lord, 1 Corinthians 8:6; but the false gods of the heathens; and Jesus Christ — As their prophet, priest, and king: this is life eternal — It is both the way to, and the essence of, everlasting happiness.
