Contradiction with Numbers 23:19
Numbers 23:19 states that God does not lie or change His mind, suggesting certainty in His word, which complements rather than contradicts Isaiah 55:11.
Numbers 23:19: God [is] not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do [it]? or hath he spoken, and shall he not make it good?
Contradiction with 1 Samuel 15:29
This verse affirms that God does not change His mind, consistent with the reliable nature of God's word in Isaiah 55:11 instead of contradicting it.
1 Samuel 15:29: And also the Strength of Israel will not lie nor repent: for he [is] not a man, that he should repent. [Strength: or, Eternity, or, Victory]
Contradiction with Jeremiah 18:10
Claims that God might change His declared actions if a nation does evil, showcasing potential divergence from the unchanging fulfillment mentioned in Isaiah 55:11.
Jeremiah 18:10: If it do evil in my sight, that it obey not my voice, then I will repent of the good, wherewith I said I would benefit them.
Contradiction with Jonah 3:10
Shows God's decision to not bring destruction upon Nineveh after repentance, which could seem to oppose the absolute certainty of fulfillment portrayed in Isaiah 55:11.
Jonah 3:10: And God saw their works, that they turned from their evil way; and God repented of the evil, that he had said that he would do unto them; and he did [it] not.
Contradiction with Ezekiel 33:13
Indicates that a righteous man could die despite his righteousness if he turns to sin, seemingly conflicting with the deterministic result implied in Isaiah 55:11.
Ezekiel 33:13: When I shall say to the righteous, [that] he shall surely live; if he trust to his own righteousness, and commit iniquity, all his righteousnesses shall not be remembered; but for his iniquity that he hath committed, he shall die for it.
Paradox #1
Isaiah 55:11 suggests that God's words always achieve their purpose and succeed in what they are intended to do. A potential contradiction here could be the idea of free will. If God's words and plans always succeed, it raises questions about human freedom to make choices and the existence of evil or suffering in the world. If everything happens according to divine purpose, it could conflict with the belief that people have the freedom to choose their actions.
