1:18 at any time. This passage confirms that on any of the many occasions in ancient times when God showed Himself in one way or another to man (e.g., Genesis 18:2; Job 42:5), we can be sure that each time it was a theophany, in which the triune God manifested Himself through the Second Person of the Godhead, the Word of God.
1:18 bosom of the Father. The Son is eternally in the Father’s “bosom” and eternally proceeding therefrom as the “only begotten Son” (Greek monogenes), uniquely different from the many other sons of God (angels are also called sons of God as are all those men and women who have been born again through faith in Christ). Those modern translators who delete the word “begotten” here are not only wrong in translation, but also in allowing dangerous heresy in the understanding of the nature of Christ.
1:18 declared. As the living Word, the Son reveals and speaks for the Father.
