Contradiction with Jeremiah 17:10
This verse states that the Lord searches the heart and tests the mind, which aligns with Psalms 44:21 rather than contradicting it, as both emphasize God's knowledge of human hearts.
Jeremiah 17:10: I the LORD search the heart, [I] try the reins, even to give every man according to his ways, [and] according to the fruit of his doings.
Contradiction with 1 Kings 8:39
This verse mentions that God alone knows the hearts of all men, consistent with Psalms 44:21 in recognizing God’s ability to discern human heart secrets.
1 Kings 8:39: Then hear thou in heaven thy dwelling place, and forgive, and do, and give to every man according to his ways, whose heart thou knowest; (for thou, [even] thou only, knowest the hearts of all the children of men;)
Contradiction with 1 Samuel 16:7
Here it's declared that God looks at the heart rather than outward appearance, which similarly underscores God’s insight into human hearts as noted in Psalms 44:21.
1 Samuel 16:7: But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for [the LORD seeth] not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart. [outward...: Heb. eyes]
Contradiction with 1 Chronicles 28:9
This verse conveys the belief that the Lord searches every heart, paralleling Psalms 44:21 in affirming God’s awareness of the hidden intents of hearts.
1 Chronicles 28:9: And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind: for the LORD searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.
Contradiction with Jeremiah 11:20
This passage highlights God's role as the one who tests the heart and mind, aligning with the claim in Psalms 44:21 about God knowing the secrets of the heart.
Jeremiah 11:20: But, O LORD of hosts, that judgest righteously, that triest the reins and the heart, let me see thy vengeance on them: for unto thee have I revealed my cause.
Paradox #1
Psalms 44:21 suggests that God knows the secrets of the heart. A possible contradiction or conflict could arise from the idea that while God is all-knowing, humans are given free will and expected to live righteously. If God already knows our true thoughts and intentions, it raises questions about the purpose and fairness of judgment based on actions versus inner thoughts. This could lead to confusion about personal accountability and the nature of free will.
