Seasonable truths in evil-times in several sermons / lately preached in and about London

And indeed it is such a sin, as hardens insensibly, that we cannot perceive: You can see the tree, the body of the tree, and the bark of the tree, and the boughs of the tree, and the leaves of the tree, but you cannot see the root of the tree. Unbelief is a root sin, and that's least perceived: Now when one hath to deal with a deceitful enemy, that is least perceived, had be not need take heed? Take heed of departing from God, through an evil heart of unbelief.

Quest. The question then is, What shall we do? These are declining and departing times, wherein many do and will depart from God, (make account on't) what shall we do that we may not depart from God through unbelief? What shall we do, that we may take heed of an unbelieving heart, that we may take heed of departing from God? (I put them together into one question) Now I shall give several directions here, and so wind up.

1. If you would not depart from God through unbelief, in declining and departing times, be sure that you keep close unto the word of God, unto his ⟨p. 225⟩appointments; and take heed how you meddle with any appointments that are like to his: For the more you depart from the word, the more you depart from God; and the more you meddle with appointments that are like to Gods, the more you depart from the word.

Thou shalt make it an oil of holy ointment, an ointment compound after the art of the Apothecary: it shall be an holy anointing oil: Well at the 33 ver. Whosoever compoundeth any like it, or whosoever putteth any of it upon a stranger, shall even be cut off from his people: You shall make none like it. At the 34 ver. You have directions for the making of an holy perfume, The Lord said unto Moses, Take unto thee sweet spices, Stacte, and Onycha, and Galbanum: these sweet spices with pure frankincense, of each shall there be a like weight: And thou shalt make it a Perfume, a Confection after the Art of the Apothecary, tempered together pure and holy: But then at the 38 ver. Whosoever shall make like unto that, to smell thereto, shall even be cut off from his people: A dangerous thing it is to meddle with the appointments in the Worship and Service of God, that are like to Gods appointments: for any man (like an Apothecary and a Confectioner) in the Worship and Service of God; To make appointments in Gods
