Contradiction with 1 John 4:17
This verse speaks of having boldness in the day of judgment, which contrasts with Isaiah 6:5, where Isaiah expresses woe and unworthiness before God.
1 John 4:17: Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world. [our love: Gr. love with us]
Contradiction with Romans 8:1
Declares that there is no condemnation for those in Christ Jesus, while Isaiah 6:5 reflects a sense of condemnation and realization of sin.
Romans 8:1: [There is] therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Contradiction with 2 Timothy 1:7
States that God has not given us a spirit of fear, contradicting the fear and trembling expressed by Isaiah in Isaiah 6:5.
2 Timothy 1:7: For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
Contradiction with Hebrews 10:19-22
Encourages believers to enter the holiest with boldness, in contradiction to Isaiah’s fearful and unworthy reaction in Isaiah 6:5.
Hebrews 10:19-22: Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus, [boldness: or, liberty]
Contradiction with Philippians 4:13
Asserts the power and strength through Christ, differing from the sense of inadequacy and despair in Isaiah 6:5.
Philippians 4:13: I can do all things through Christ which strengtheneth me.
Contradiction with Ephesians 3:12
Speaks of having boldness and access with confidence through faith, opposing Isaiah's reaction of dread and ruin in 6:5.
Ephesians 3:12: In whom we have boldness and access with confidence by the faith of him.
Contradiction with 2 Corinthians 5:17
Conveys the idea of being a new creation and not being held back by past unworthiness, unlike Isaiah’s lament of being undone due to unclean lips in Isaiah 6:5.
2 Corinthians 5:17: Therefore if any man [be] in Christ, [he is] a new creature: old things are passed away; behold, all things are become new. [he is: or, let him be]
Paradox #1
Isaiah 6:5 expresses a sense of unworthiness and an encounter with divine holiness. A possible contradiction might be the idea that humans are inherently sinful and unclean while being created in the image of God, who is perfect. This could create a conflict between the belief in inherent human flaws and the belief in the goodness of God's creation.
