worship of his own invention, agreeable to his own humor and design, as (Isa. lviii. 2) it is said, they “delighted in approaching to God;” but it was for carnal ends. Novelty engenders complacency; but it must be a worship wherein God will delight; and that must be a worship according to his own rule and infinite wisdom, and not our shallow fancies. God requires a cheerfulness in his service, especially under the gospel, where he sits upon a throne of grace; discovers himself in his amiableness, and acts the covenant of grace, and the sweet relation of a father. The priests of old were not to sully themselves with any sorrow, when they were in the exercise of their functions. God put a bar to the natural affections of Aaron and his sons, when Nadab and Abihu had been cut off by a severe hand of God (Lev. x. 6). Every true Christian in a higher order of priesthood, is a person {a236} dedicated to joy and peace, offering himself a lively sacrifice of praise and thanksgiving; and there is no christian duty, but is to be set off and seasoned with cheerfulness: he that loves a cheerful giver in acts of charity, requires no less a cheerful spirit in acts of worship; as this is an ingredient in worship, so it is the means to make your spirits intent in worship. When the heart triumphs in the consideration of divine excellency and goodness, it will be angry at anything that offers to jog and disturb it. 7. Spiritual worship is to be performed, though with a delight in God, yet with a deep reverence of God. The gospel, in advancing the spirituality of worship, takes off the terror, but not the reverence of God; which is nothing else in its own nature, but a due and high esteem of the excellency of a thing according to the nature of it; and, therefore, the gospel presenting us with more illustrious notices of the glorious nature of God, is so far from indulging any disesteem of him, that it requires of us a greater reverence suitable to the height of its discovery, above what could be spelt in the book of creation; the gospel worship is therefore expressed by trembling (Hos. xi. 10): “They shall walk after the Lord; he shall roar like a lion; when he shall roar, then the children shall tremble from the West.” When the lion of the tribe of Judah shall lift up his powerful voice in the gospel, the western Gentiles shall run trembling to walk after the Lord. God hath alway attended his greatest manifestations with remarkable characters of majesty, to create a reverence in his creature: he caused the “wind to march before him,” to cut the mountain, when he manifested himself to Elijah (1 Kings xix. 11); “A wind and a cloud of fire,” before that magnificent vision to Ezekiel (chap. i. 4, 5); “Thunders and lightnings” before the giving the law (Exod. xix. 18); and a “mighty wind” before the giving the Spirit (Acts ii.): God requires of us an awe of him in the very act of performance. The angels are pure, and cannot fear him as sinners, but
