12. That the old baptism should cease, and a new one should begin. In Isaiah: “Therefore remember ye not the former things, neither reconsider the ancient things. Behold, I make new the things which shall now arise, and ye shall know it; and I will make in the desert a way, and rivers in a dry place, to give drink to my chosen race, my people whom I acquired, that they should show forth my praises.” 3868 In the same also:  “If they thirst, He will lead them through the deserts; He will bring forth water from the rock; the rock shall be cloven, and the water shall flow: and my people shall drink.” 3869   Moreover, in the Gospel according to Matthew, John says: “I indeed baptize you with water unto repentance: but He that cometh after me is mightier than I, whose shoes I am not worthy to bear; He shall baptize you with the Holy Ghost, and with fire.” 3870 Also according to John: “Except a man be born of water, and of the Spirit, he cannot enter into the kingdom of God. For that which is born of the flesh is flesh, and that which is born of the Spirit is spirit.” 3871 3868     Isa. xliii. 18–21 . 3869     Isa. xlviii. 21 . 3870     Matt. iii. 11 . 3871     John iii. 5, 6 .
