"The true light that gives light to everyone was coming into the world. He was in the world, and the world was made through him, yet the world did not know him.
He came to his own, and his own people did not receive him.
But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God." John 1:9-13
Gill's Exposition of the Entire Bible:
"No man is left without some direct communication of light from the Father of lights. That light may be quenched, the eye of the soul may be blinded, the folly of the world may obscure it as a cloud disperses the direct rays of the sun; but a fundamental fact remains - the veritable Light illumines every man."
His own people did not receive him "...in the terrible record of his rejection by his own people, by his own disciples, by the theocratic chiefs, by the assembled Sanhedrin, by the very populace to whom Pilate appealed to save him from murderous fury."
"Which were born not of blood',.... Or bloods, in the plural number. The birth, here spoken of, is regeneration, expressed by a being born again, or from above; by a being quickened by the Spirit and grace of God; by Christ being formed in men; and by a partaking of the divine nature; and by being made new creatures, as all that believe in the name of Christ are."
