Chapters XXXIII., XXXIV., XXXV., XXXVI.--The saving nature of Baptism depends on three things; Prayer, Water, and Faith. 1. It is shown how Prayer secures the Divine Presence. God is a God of truth; and He has promised to come (as Miracles prove that He has come already) if invoked in a particular way. 2. It is shown how the Deity gives life from water. In human generation, even without prayer, He gives life from a small beginning. In a higher generation He transforms matter, not into soul, but into spirit. 3. Human freedom, as evinced in faith and repentance, is also necessary to Regeneration. Being thrice dipped in the water is our earliest mortification; coming out of it is a forecast of the ease with which the pure shall rise in a blessed resurrection: the whole process is an imitation of Christ.
