Chapter 18 — Of the Assurance of Grace and Salvation
Section 3. This infallible assurance doth not so belong to the essence of faith, but that a true believer may wait long and conflict with many difficulties before he be partaker of it; yet being enabled by the Spirit to know the things which are freely given him of God, he may, without extraordinary revelation, in the right use of means, attain thereunto: and therefore it is the duty of every one to give all diligence to make his calling and election sure, that thereby his heart may be enlarged in peace and joy in the Holy Spirit, in love and thankfulness to God, and in strength and cheerfulness in the duties of obedience, the proper fruits of this assurance; it being far from inclining men to looseness.
