Although I am forced at the present, to be at a distance from you, yet I would not have you ignorant, that the dear remembrance of you is always fresh with me, and the care of your eternal welfare is always living upon my heart. Therefore as my beloved Friends I warn you, and cease not to stir you up by way of remembrance, being jealous for you with a Godly jealousy, that no man take your Crown. My dearly Beloved, I know you have many enemies, and above all, I fear your bosom Enemies: and as the Watchman of the Lord, I give you careful warning, and exhort you all not to be high-minded, but fear. Blessed is the man that feareth always. Look diligently, lest any of you fail of the Grace of God. You have made much and long Profession of the Name of Jesus Christ: Oh look to your foundations, see upon what ground you stand. Look to your sincerity. You must every one of you stand shortly before the Judgement ⟨p. 81⟩Seat of Christ, and be tried for your lives: Oh, try your selves throughly first. 'Tis easy to mistake Education for Regeneration, and common Conviction and Illumination for Conversion, and a partial Reformation and external Obedience, •or true Sanctification. Therefore I beseech you every one, to examine whether you are in the Faith. Prove your own selves. Tell not me, you hope you are sincere, you hope you shall go to Heaven: Never put it off with hopes, but pray, and try, and search, till you are able to say, yea, and know you are passed from death to life, and that you know you have a Building, not made with hands, eternal in the Heavens.
