My design in appearing once more in print is not to please the captious critic, or the sullen cynic-but to heighten your "fellowship with the Father and the Son," 1 John 1:3-4, and to further you in a closer walking with God, and to ripen you more and more for reigning with God when you shall be here no more. "Beloved in our Lord," there are two sad and great evils among the saints this day. The strong are very apt, yes, they make little of offending the weak; and the weak are as apt, and make as little of judging and condemning the strong. The serious and conscientious perusal of this treatise may, by the blessing of the Lord, contribute much to the preventing of those sad evils. You who are weak may, in this treatise, as in a mirror, see your weakness, your mercies, your graces, your duties, your privileges, and your comforts. You who are weak in grace, may here find many questions answered and doubts resolved, that tend to the satisfying, quieting, settling, and establishing of your precious souls in peace, joy, and assurance. You who are weak in grace, may here find a staff to support you, a light to direct you, a sword to defend you, and a cordial to strengthen you, etc. And you who are strong in grace, may here see what is your way, what is your work, and what at last shall be your reward. Here you will find that which tends to the discovery of spirits, the sweetening of spirits, the uniting of spirits, the healing of spirits, and the making up of breaches, etc. Here you will find "the unsearchable riches of Christ" opened. In Christ are riches of justification; in Christ are riches of sanctification, riches of consolation, and riches of glorification. And this following treatise may serve as a golden key, to open the door, that you may come where these treasures lie.
