Colossians 1:17 - Matthew Poole's English Annotations on the Holy Bible

And he is before all things: to obviate all exceptions to what he had said before, the apostle doth expressly assert (what was implied before) Christ's pre-existence to all the things that were created, and therefore that he himself was not made, but eternally begotten, and so did exist, and was actually before all creatures in causality, dignity, and time; which proves his eternity, (consonant to other scriptures, Proverbs 8:22 Isaiah 44:6 Micah 5:2 1 Thessalonians 1:1, 1 Thessalonians 17:5 Revelation 1:8,11,17 Re 22:13), because before all things there was nothing but proper eternity, Psalms 90:2. And by him all things consist: then follows this further argument of Christ's excellency and perfection, that he is not only the Creator or Founder, but likewise the Supporter or Upholder, of all things whatsoever are created, yea, even of the most excellent and useful of them, who in him do live and move, Acts 17:28 Hebrews 1:3: he being the conservant as well as procreant cause of the heavens and earth, with all things therein, because in respect of God it is the same action which is continued in conservation and providence whielt was in creation, not breaking off the same influence which was exerted in producing them out of nothing into being, Isaiah 46:4 1 Thessalonians 5:19.
