3. Spiritual worship is done with sincerity. When the heart stands right to God, and the soul performs what it pretends to perform; when we serve God with our spirits, as the apostle (Rom. i. 9), “God is my witness, whom I serve with my spirit in the gospel of his Son:” this is not meant of the Holy Ghost; for the apostle would never have called the Spirit of God his own spirit; but with my spirit, that is, a sincere frame of heart. A carnal worship, whether under the law or gospel, is, when we are busied about external rites, without an inward compliance of soul. God demands the heart; “My son, give me thy heart;”[490] not give me thy tongue, or thy lips, or thy hands; these may be given without the heart, but the heart can never be bestowed without these as its attendants. A heap of services can be no more welcome to God, without our spirits, than all Jacob’s sons could be to Joseph, without the Benjamin he desired to see. God is not taken with the cabinet, but the jewel; he first respected Abel’s faith and sincerity, and then his sacrifice; he disrespected Cain’s infidelity and hypocrisy, and then his offering. For this cause he rejected the offerings of the Jews, the prayers of the Pharisees, and the alms of Ananias and Sapphira, because their hearts and their duties were at a distance from one another. In all spiritual sacrifices, our spirits are God’s portion. Under the law, the reins were to be consumed by the fire on the altar, because the secret intentions of the heart were signified by them (Psalm vii. 9), “The Lord trieth the heart and the reins.” It was an ill omen among the heathen, if a victim wanted a heart. The widow’s mites, with her heart in them, were more esteemed than the richer offerings without it.[491] Not the quantity of service, but the will in it, is of account with this infinite Spirit. All that was to be brought for the framing of the tabernacle was to be offered “willingly with the heart.”[492] The more of will, the more of spirituality and acceptableness to God (Psalm cxix. 108), “Accept the free‑will offering of my lips.” Sincerity is the salt which seasons every sacrifice. The heart is most like to the object of worship; the heart in the body is the spring of all vital actions; and a spiritual soul is the spring of all spiritual actions. How can we imagine God can delight in the mere service of the body, any more than we can delight in converse with a carcass? Without the heart it is no worship; it is a stage play; an acting a part without being that person really which is acted by us: a hypocrite, in the notion of the word, is a stage‑player. We may as well say a man may believe with his body, as worship God only with his body. Faith is a great ingredient in worship; and it is “with the heart man believes unto righteousness.”[493] We may be truly said to worship God, {a226} though we want perfection; but we cannot be said to worship him, if we want sincerity; a statue
