Genesis 1:3

God said Not by an articulate voice; for to whom should he speak? but in his own eternal mind. He willed that the effect here mentioned should be produced, and it was produced. This act of his almighty will is termed, Hebrews 1:3, the word of his power. Perhaps, however, his substantial Word, his Son, by whom he made the worlds, Hebrews 1:2, and Psalms 33:6; Psalms 33:9, is here intended, and whom the ancient fathers of the Christian Church thought to be termed the Word, John 1:1, chiefly for this reason. Let there be light, &c. The noted critic, Longinus, in his celebrated Treatise on the Sublime, expresses his admiration of this sentence, as giving a most just and striking idea of the power of God. In bringing order out of confusion, and forming the sundry parts of the universe, God first gave birth to those that are the most simple, pure, active, and powerful; which he, probably, afterward used as agents or instruments in forming some other parts. Light is the great beauty and blessing of the universe; and as it was the first of all visible things, so, as the firstborn, it most resembles its great parent in purity and power, in brightness and beneficence. Probably the light was at first impressed on some part of the heavens, or collected in some lucid body, the revolution of which distinguished the three first days. On the fourth it was condensed, increased, perfected, and placed in the body of the sun and other luminaries.
