9. Spiritual worship is to be performed with holiness. God is a holy Spirit; a likeness to God must attend the worshipping of God as he is; holiness is alway in season; “It becomes his house forever” (Psalm xci. 5). We can never serve the living God till we “have consciences purged from dead works” (Heb. ix. 14). Dead works in our consciences are unsuitable to God, an eternal living Spirit. The more mortified the heart, the more quickened the service. Nothing can please an infinite purity but that which is pure; since God is in his glory, in his ordinances, we must not be in our filthiness. The holiness of his Spirit doth sparkle in his ordinances; the holiness of our spirits ought also to sparkle in our observance of them. The holiness of God is most celebrated in the worship of angels;521 spiritual worship ought to be like angelical; that cannot be with souls totally impure. As there must be perfect holiness to make a worship perfectly spiritual; so there must be some degree of holiness to make it in any measure spiritual. God would have all the utensils of the sanctuary employed about his service to be holy; the inwards of the sacrifice were to be rinsed thrice.522 The crop and feathers of sacrificed doves were to be hung eastward towards the entrance of the temple, at a distance from the holy of holies, where the presence of God was most eminent (Lev. i. 16). When Aaron was to go into the holy of holies, he was to “sanctify himself” in an extraordinary manner (Lev. xvi. 4). The priests were to be bare‑footed in the temple, in the exercise of their office; shoes alway were to be put off upon holy ground: “Look to thy foot when thou goest to the house of God,” saith the wise man (Eccles. v. 1). Strip the affections, the feet of the soul, of all the dirt contracted; discard all earthly and base thoughts from the heart. A beast was not to touch the Mount Sinai, without losing his life; nor can we come near the throne with brutish affections, without losing the life and fruit of the worship. An unholy soul degrades himself from a spirit to a brute, and the worship from spiritual to brutish. If any unmortified sin be found in the life, as it was in the comers to the temple, it taints and pollutes the worship (Isa. i. 15). All worship is an acknowledgment of the excellency of God as he is holy; hence it is called, a “sanctifying God’s name” (Jer. vii. 9, 10); how can any person sanctify God’s name that hath not a holy resemblance to his nature? If he be not holy as he is holy, he cannot worship him according to his excellency in spirit and in truth; no worship is spiritual wherein we have not a communion with God. But what intercourse can there be between a holy God, and an impure creature; between light and darkness? We have no fellowship with him in any service, unless “we walk in the light,” in service and out of service, as he is light (1 John i. 7). The heathen thought not their sacrifices agreeable to God without washing their hands; whereby they signified the preparation of their hearts, before they made the oblation: clean hands without a pure heart, signify nothing; the frame of our hearts must answer the purity of the outward symbols (Psalm xxvi. 6): “I will wash my hands in innocence, so will I compass thine altar, O Lord;” he would observe the appointed ceremonies, but not without “cleansing his heart as well as his hands.” Vain man is apt to rest upon outward acts and rites of worship; but this must alway be practised; the words are in the present tense, “I wash,” “I compass.” Purity in worship ought to be our continual care. If we would perform a spiritual service, wherein we would have communion with God, it must be in holiness; if we would walk with Christ, it must be in “white” (Rev. iii. 4), alluding to the white garments the priests put on, when they went to perform their service; as without this we cannot see God in heaven, so neither can we see the beauty of God in his own ordinances.
10. Spiritual worship is performed with spiritual ends, with raised aims at the glory of God. No duty can be spiritual that hath a carnal aim; where God is the sole object, he ought to be the principal end; in all our actions he is to be our end, as he is the principle of our being; much more in religious acts, as he is the object of our worship. The worship of God in Scripture is expressed by the “seeking of him” (Heb. xi. 6); him, not ourselves; all is to be referred to God. As we are “not to live to ourselves, that being the sign of a carnal state, so we are not to worship for ourselves” (Rom. xiv. 7, 8). As all actions are denominated good from their end, as well as their object, so upon the same account they are denominated spiritual. The end spiritualizeth our natural actions, much more our religious; then are our faculties devoted to him when they centre in him. If the intention be evil, there is nothing but darkness in the whole service (Luke xi. 34). The first institution of the Sabbath, the solemn day for worship, was to contemplate the glory of God in his stupendous works of creation, and render him a homage for them (Rev. iv. 11): “Thou art worthy, O Lord, to receive honor, glory, and power; for thou hast created all things, and for thy pleasure they are and were created.” No worship can be returned without a glorifying of God; and we cannot actually glorify him, without direct aims at the promoting his honor. As we have immediately to do with God, so we are immediately to mind the praise of God. As we are not to content ourselves with habitual grace, but be rich in the exercise of it in worship, so we are not to acquiesce in the habitual aims at the glory of God, without the actual overflowings of
