In him was life
The Persic version reads in the plural number, "lives". There was life in the word with respect to himself; a divine life, the same with the life of the Father and of the Spirit; and is in him, not by gift, nor by derivation or communication; but originally, and independently, and from all eternity: indeed he lived before his incarnation as Mediator, and Redeemer. Job knew him in his time, as his living Redeemer; but this regards him as the word and living God, and distinguishes him from the written word, and shows that he is not a mere idea in the divine mind, but a truly divine person: and there was life in Christ the word, with respect to others; the fountain of natural life is in him, he is the efficient cause, and preserver of it; whether vegetative, animal, or rational; and proves him to be truly God, and that he existed before his incarnation; since creatures, who have received such a life from him, did: and spiritual life was also in him; all his elect are dead in trespasses and sins, and cannot quicken themselves. Christ has procured life for them, and gives it to them, and implants it in them; a life of sanctification is from him; and a life of justification is upon him, and of faith is by him; all the comforts of a spiritual life, and all things appertaining to it, are from him, and he maintains, and preserves it. Eternal life is in him, and with him; not the purpose of it only, nor the promise of it barely, but the gift of it itself; which was granted in consequence of his asking it, and which he had by way of stipulation; and hence has a right and power to bestow it: now, this being in him proves him to be the true God, and shows us where life is to be had, and the safety and security of it:
and the life was the light of men;
the life which was in, and by the word, was, with respect to men, a life of light, or a life attended with light: by which is meant, not a mere visive faculty, receptive of the sun's light, but rational knowledge and understanding; for when Christ, the word, breathed into man the breath of life, and he became a living soul, he filled him with rational light and knowledge. Adam had a knowledge of God; of his being, and perfections; of the persons in the Trinity; of his relation to God, dependence on him, and obligation to him; of his mind and will; and knew what it was to have communion with him. He knew much of himself, and of all the creatures; this knowledge was natural and perfect in its kind, but loseable; and different from that which saints now have of God, through Christ, the Mediator; and since this natural light was from Christ, the word, as a Creator, he must be the eternal God. The Socinians are not willing to allow this sense, but say that Christ is the light of men, by preaching the heavenly doctrine, and by the example of his holy life; but hereby he did not enlighten every man that cometh into the world; the greatest part of men, before the preaching, and example of Christ, sat in darkness; and the greatest part of the Jews remained in darkness, notwithstanding his preaching, and example; and the patriarchs that were enlightened under the former dispensation, were not enlightened this way: it will be owned, that all spiritual and supernatural light, which any of the sons of men have had, since the fall, was from Christ, from whom they had their spiritual life; even all spiritual light in conversion, and all after degrees of light; through him they enjoyed the light of God's countenance, and had the light of joy and gladness here, and of glory hereafter.
