2. Under the new covenant or testament, however, these promised blessings are not given to all men, because God is true, thus the covenant is necessarily discriminate. These blessings are given, however, doubly when the covenant is received. In the first place, by the substance of the covenant itself or by the promised blessings from God themselves, then by their administration in the visible assembly. In the first sense (learned from Jeremiah in the place already cited), which substance also is peculiar to the elect. For to all the elect and to them alone, this part, the remission of sins, renewal to the image of God, and the knowledge of God itself is therefor promised, or which embraces God’s favor which they would never have had from themselves (John 6:44,45; 64,65; 10:26; 11:52; Acts 13:47,48; Romans 8:29,30; 9:7,8,9,11,15,16; Titus 1:1).
