Charles Spurgeon Commentary John 1:13

"who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God." — John 1:13 (ASV)

Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.

There is another birth besides the natural one. Never does the birth of the flesh make us Christians. If our ancestry were a line of saints, yet we are born sinners. We must be born again if we are to become saints. If we could trace our pedigree to a perfect man—if such a one exists—yet the birth by the flesh would not benefit us. Sons of God are: born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.

Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.

So that those who receive Christ, those who truly believe on Christ, are people who have been born, as others have not been born, by a new birth from heaven, a supernatural birth, so that they are a people set apart by themselves as those who have been twice created, first as human beings just like others, and then as new creatures in Christ Jesus.
