This infallible assurance is not so joined to the essence of faith that it is an automatic and inevitable experience. A true believer may wait long and fight with many difficulties before he becomes a partaker of it. Yet, being enabled by the Spirit to know the things which are freely given to him by God, he may, without any extraordinary revelation attain this assurance by using the means of grace in the right way. Therefore it is the duty of everyone to give the utmost diligence to make his calling and election sure, so that his heart may be enlarged in peace and joy in the Holy Spirit, in love and thankfulness to God, and in strength and cheerfulness for carrying out the duties of obedience. These duties are the natural fruits of assurance, for it is far from inclining men to looseness [i.e., to be unrestrained in their behavior].
