John 1.13

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

The sons of God, those who believed 'on his name', those who 'received him', those to whom he gave 'power to become the sons of God,' were born of woman, of course, but in their true eternal life they were born of God.
Many wishful thinkers like to believe that God resides in all of us, that all of us are chosen by God. Then there are others who like who like to believe that they are responsible for their belief, that somehow, for all their human fraility, they have found God, made a decision, accepted the Almighty. but they are no more active in their birth in Christ than a new born baby is active in her emergence from her mother's womb.
The sons of God are not are not born 'of blood' or 'of the will of the flesh', nor 'of the will of the man', but solely, wholly completely of the will of God.
The heathen enjoys the Common Grace of the beauties of and the joys of this world, of love and laughter and prosperity, as well as the fruits of Common Sin, but the heathen lives absorbed in himself, above him only sky, and when his hour comes, he will suffer eternal death.
But the sons of God can praise the Lord in this world, and bask in his Eternal Truth for ever more, the sons of God, the Elect, born of the will of God.
