_Inference 7._ If God be a Spirit, let us take heed of those sins which are spiritual. Paul distinguisheth between the filth of the flesh, and that of the spirit.[415] By the one we defile the body; by the other we defile the spirit, which, in regard of its nature, is of kin to the Creator. To wrong one who is near of kin to a prince, is worse than to injure an inferior subject. When we make our spirits, which are most like to God in their nature, and framed according to his image, a stage to act vain imaginations, wicked desires, and unclean affections, we wrong God in the excellency of his work, and reflect upon the nobleness of the pattern; we wrong him in that part where he hath stamped the most signal character of his own spiritual nature; we defile that whereby we have only converse with him as a Spirit, which he hath ordered more immediately to represent him in this nature, than all corporeal things in the world can, and make that Spirit with whom we desire to be joined unfit for such a knot. God’s spirituality is the root of his other perfections. We have already heard he could not be infinite, omnipresent, immutable, without {a204} it. Spiritual sins are the greatest root of bitterness within us. As grace in our spirits renders us more like to a spiritual God, so spiritual sins bring us into a conformity to a degraded devil.[416] Carnal sins change us from men to brutes, and spiritual sins divest us of the image of God for the image of Satan. We should by no means make our spirits a dunghill, which bear upon them the character of the spiritual nature of God, and were made for his residence. Let us, therefore, behave ourselves towards God in all those ways which the spiritual nature of God requires us. {a205} DISCOURSE IV. ON SPIRITUAL WORSHIP. JOHN iv. 24.――God is a Spirit: and they that worship him must worship him in spirit and in truth. HAVING thus despatched the first proposition, “God is a Spirit,” it will not be amiss to handle the inference our Saviour makes from that proposition, which is the second observation propounded. _Doct._ That the worship due from us to God ought to be spiritual, and spiritually performed. Spirit and truth are understood variously. We are to worship God,
