Contradiction with Numbers 23:19
God is not a man, that he should lie; neither the son of man, that he should repent: this suggests no change, contradicting the idea of gifts being irrevocable.
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 Hebrews 6:4-6
It is impossible for those who were once enlightened to renew them again unto repentance, implying a possibility of falling away, which contradicts irrevocability.
Hebrews 6:4-6: For [it is] impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
Contradiction with 1 Samuel 15:11
God repented that he had made Saul king, suggesting that divine choices can be revoked, contradicting the permanence of God's gifts and calling.
1 Samuel 15:11: It repenteth me that I have set up Saul [to be] king: for he is turned back from following me, and hath not performed my commandments. And it grieved Samuel; and he cried unto the LORD all night.
Paradox #1
Some people might see a contradiction between Romans 11:29 and other parts of the Bible that talk about God changing His mind or punishing people. Romans 11:29 suggests that God's gifts and calling are constant and unchanging. However, other stories in the Bible show instances where God seems to change His plans or react to human actions. This could create confusion about whether God is always unchanging or if He sometimes adapts based on circumstances.
Paradox #2
The potential doctrinal conflict with the verse could be regarding the idea of God's gifts and calling being unchangeable or irrevocable. Some might see this as conflicting with the notion of free will and the possibility of losing salvation or falling out of favor with God. However, interpretations vary, and many find ways to harmonize these ideas within broader theological frameworks.
