Contradiction with Ecclesiastes 9:5
This verse implies the dead know nothing, which is consistent with the message of Isaiah 38:18 rather than contradictory.
Ecclesiastes 9:5: For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.
Contradiction with Philippians 1:23
This verse expresses a desire to depart and be with Christ after death, which contrasts with the idea that the dead cannot praise God, implying a form of continued existence.
Philippians 1:23: For I am in a strait betwixt two, having a desire to depart, and to be with Christ; which is far better:
Contradiction with 2 Corinthians 5:8
This verse suggests being absent from the body is being present with the Lord, indicating a form of existence after death which contrasts with the silence attributed to Sheol in Isaiah 38:18.
2 Corinthians 5:8: We are confident, [I say], and willing rather to be absent from the body, and to be present with the Lord.
Paradox #1
Some people might see a conflict with the idea of the afterlife. In some parts of the Bible, there is a belief in life after death and the soul praising God in heaven. However, this verse suggests that those who have died cannot praise or thank God, which seems to disagree with the belief in an active afterlife where worship continues.
Paradox #2
The contradiction or inconsistency could arise from the idea that this verse suggests a specific limitation on who can offer praise or express gratitude, which might conflict with the belief that all beings are valuable and capable of worship regardless of their circumstances. This could be seen as inconsistent with more inclusive interpretations of faith and worship.
