The grace of the Spirit takes possession of the quiet soul, and gives it a taste of the unspeakable good things to come, which no passionate and negligent eye has seen, nor ear heard, neither have entered into the heart of such a man (cf. I Cor. 2:9). This taste is the earnest of these good things, and the heart which accepts these pledges becomes spiritual and receives assurance of its salvation.
