24.God is a Spirit. This is a confirmation drawn from the very nature of God. Since men are flesh, we ought not to wonder, if they take delight in those things which correspond to their own disposition. Hence it arises, that they contrive many things in the worship of God which are full of display, but have no solidity. But they ought first of all to consider that they have to do with God, who can no more agree with the flesh than fire with water. This single consideration, when the inquiry relates to the worship of God, ought to be sufficient for restraining the wantonness of our mind, that God is so far from being like us, that those things which please us most are the objects of his loathing and abhorrence. And if hypocrites are so blinded by their own pride, that they are not afraid to subject God to their opinion, or rather to their unlawful desires, let us know that this modesty does not hold the lowest place in the true worship of God, to regard with suspicion whatever is gratifying according to the flesh. Besides, as we cannot ascend to the height of God, let us remember that we ought to seek from His word the rule by which we are governed. This passage is frequently quoted by the Fathers against the Arians, to prove the Divinity of the Holy Spirit, but it is improper to strain it for such a purpose; for Christ simply declares here that his Father is of a spiritual nature, and, therefore, is not moved by frivolous matters, as men, through the lightness and unsteadiness of their character, are wont to be.
