Treasury of Scripture Knowledge
Isaiah had said these things because he saw the [coming] glory of Jesus, and [so] was speaking about Him.
Jesus replied to him, "Have I been with you men all this time, and [still] you do not know me, Philip? The person who has seen me, has [also] seen the Father. How can you say, 'Show us the Father'?
If I had not performed the [miraculous] deeds among them which no one else had done, they would not be guilty of sinning. But now they have both seen and hated both me and my Father.
2 Corinthians 4:6
For God, who said [Gen. 1:3], "Light will shine out of darkness," has [also] shone in our hearts to provide [us with] the light of the knowledge of God's splendor [as it shines] on the face of Christ. [Note: This allusion to "splendor shining on Christ's face" may be a continuation of the analogy used in 3:13].
He is the image of the invisible God, the firstborn One [i.e., who takes preeminence] over all that is created.
This Son expresses the radiance of God's splendor and represents His very Being, and He sustains everything by His powerful word. After He had provided cleansing for [man's] sins, He sat down at the right side of the Majesty [i.e., God] on high [i.e., in heaven].
1 John 5:20
And [in addition], we know that the Son of God has come [in a physical body, See 4:2] and has given us understanding, so that we can know the True One [i.e., God], and that we are in [fellowship with] the True One, even His Son Jesus Christ. This Son is the true God and eternal life.
