“We should pray that God would enrich his ordinance with his presence; that he would make the sacrament effectual to all those holy ends and purposes for which he hath appointed it; that it may be the feast of our graces, and the funeral of our corruptions; that it may not only be a sign to represent, but an instrument to convey, Christ to us, and a seal to assure us of our heavenly jointure [union].”
