I Must say of you as David did of Jonathan, Very pleasant have you been unto me, and your love to me is wonderful. And as I have formerly taken great content in that my Lot was cast among you, so through grace I rejoice in my present Lot, that I am called to approve my love to you by suffering for you; for you, I say: for you know that I have not sought yours but you; and that for doing my duty to your souls, I am here in these Bonds, which I do cheerfully accept through the grace of God that strengtheneth me. Oh! that your Souls might be quickened and enlarged by these my Bonds! that your hands might be strengthened, and your hearts encouraged in the Lord your God by our sufferings! See to it, my dearly Beloved, that you stand fast in the power of the Holy Doctrine which we have Preached from the Pulpit; preached at the Bar; preached ⟨p. 27⟩from the Prison to you: It is a Gospel worth the suffering for: see that you follow after holiness, without which no man shall see God: Oh! the madness of the blind World, that they should put from them the only Plank upon which they can scape to Heaven. Surely the Enemies of Holiness are their own Enemies. Alas for them! they know not what they do. What would not these foolish Virgins do at last, when it is too late for a little of the Oil of the wise; Oh, for one dram of that Grace which they have scorned and despised. But let not any of you, my dear People, be wise too late: Look diligently lest any man fail of the Grace of God. Beware that none of you be cheated through the subtlety of Satan and deceitfulness of your hearts with counterfeit gr•. There is never a grace but hath its counterfeit: and there is nothing in all the World that is more common or more easy, than to mistake common and counterfeit Grace for true and saving: and remember you are undone for evermore, if you should die in such a mistake: Not that I would shake the confidence of any sound Believer, who upon often and through scarce into the Scripture and his own heart, and putting himself upon Gods trial, hath gotten good evidence that his Graces are of the right kind: Build your confidence sure: See that you get the knowledge of the certain and infallible marks of Salvation, and make sure by great observing your own hearts that these marks be in you, and then you cannot be too confident. But as you love your souls take heed of a groundless confidence.
