John 1:4,5 - Joseph Benson’s Commentary on the Old and New Testaments

In him Or, through him, as Beza understands it; was life He was the living and powerful Word, which was the source of life to every living creature, as well as of being to all that exists. And the life was the light of men He, who is essential life, and the author of life to all that live, was also the fountain of wisdom, holiness, and happiness to man in his original state. And the light shineth in darkness Namely, in the darkness, or amid the ignorance and folly, sinfulness and wretchedness of fallen man. This has been the case from the time of man's fall, through all ages, and in all nations of the world; the light of reason and conscience, as well as the light issuing from the works of creation and providence, and the various discoveries of God and his will made to and by the patriarchs and prophets, being through and from him: But the darkness comprehended it not Did not advert to it, so as to understand and profit by it, as it might have done by the instruction thus communicated. It became necessary, therefore, in order to the more full illumination and the salvation of mankind, that God should give a more perfect revelation of his mind and will, than he had given in former ages. Of this the evangelist speaks next.
