Too late to remedy
How this joint testimony of God's Spirit and our spirit may be clearly and solidly distinguished from the presumption of a natural mind, and from the delusion of the devil, is the next thing to be considered. And it highly concerns all who desire the salvation of God to consider it with the deepest attention, as they would not deceive their own souls. An error in this is generally observed to have the most fatal consequences, the more so because the one who errs seldom discovers his mistake until it is too late to remedy it.

II. 1. How this joint testimony of God’s Spirit and our spirit, may be clearly and solidly distinguished, from the presumption of a natural mind, and from the delusion of the devil, is the next thing to be considered. And it highly imports all who desire the salvation of God, to consider it with the deepest attention, as they would not deceive their own souls. An error in this is generally observed to have the most fatal consequences: the rather, because he that errs seldom discovers his mistake, till it is too late to remedy it.
