Nicodemus answered him, "How can these things be?"
[1.] What it is that is required: to be born again; that is, First, We must live a new life. Birth is the beginning of life; to be born again is to begin anew, as those that have hitherto lived either much amiss or to little purpose. We must not think to patch up the old building, but begin from the foundation. Secondly, We must have a new nature, new principles, new affections, new aims. We must be born anothen, which signifies both denuo—again, and desuper—from above. 1. We must be born anew; so the word is taken, Galatians 4:9, and ab initio—from the beginning, Luke 1:3. By our first birth we are corrupt, shapen in sin and iniquity; we must therefore undergo a second birth; our souls must be fashioned and enlivened anew. 2. We must be born from above, so the word is used by the evangelist, John 3:31 John 19:11, and I take this to be especially intended here, not excluding the other; for to be born from above supposes being born again. But this new birth has its rise from heaven (John 1:13) and its tendency to heaven: it is to be born to a divine and heavenly life, a life of communion with God and the upper world, and, in order to this, it is to partake of a divine nature and bear the image of the heavenly.
