To conclude: God hath appointed some parts of worship which cannot be performed without the body, as sacraments; we have need of them because we are not wholly spiritual and incorporeal creatures. The religion which consists in externals only is not for an intellectual nature; a worship purely intellectual is too sublime for a nature allied to sense, and depending much upon it. The christian mode of worship is proportioned to both; it makes the sense to assist the mind, and elevates the spirit above the sense. Bodily worship helps the spiritual: the members of the body reflect back upon the heart, the voice bars distractions, the tongue sets the heart on fire in good as well as in evil. It is as much against the light of nature to serve God without external significations, as to serve him only with them without the intention of the mind. As the invisible God declares himself to men by visible works and signs, so should we declare our invisible frames by visible expressions. God hath given us a soul and body in conjunction; and we are to serve him in the same manner he hath framed us. II. The second thing I am to show is, what spiritual worship is. In general, the whole spirit is to be employed; the name of God is not sanctified but by the engagement of our souls. Worship is an act of the understanding, applying itself to the knowledge of the excellency of God and actual thoughts of his majesty; recognizing him as the supreme Lord and Governor of the world, which is natural knowledge; beholding the glory of his attributes in the Redeemer, which is evangelical knowledge. This is the sole act of the spirit of man. The same reason is for all our worship as for our thanksgiving. This must be done with understanding: (Psalm xlvii. 7) {a223} “Sing ye praise with understanding;” with a knowledge and sense of his greatness, goodness, and wisdom. It is also an act of the will, whereby the soul adores and reverences his majesty, is ravished with his amiableness, embraceth his goodness, enters itself into an intimate communion with this most lovely object, and pitcheth all his affections upon him. We must worship God understandingly; it is not else a reasonable service. The nature of God and the law of God abhor a blind offering; we must worship him heartily, else we offer him a dead sacrifice. A reasonable service is that wherein the mind doth truly act something with God. All spiritual acts must be acts of reason, otherwise they are not human acts, because they want that principle which is constitutive of man, and doth difference him from other creatures. Acts done only by sense are the acts of a brute; acts done by reason are the acts of a man. That which is only an act of sense cannot be an act of religion. The sense, without the conduct of reason, is not the subject of religious acts; for then beasts were capable of religion as well as men. There cannot be religion where there is not reason; and there
