Contradiction with Genesis 18:14
This verse states that nothing is too hard for the Lord, while Jeremiah 32:16 is a prayer acknowledging God’s power, so there is no direct contradiction.
Genesis 18:14: Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son.
Contradiction with Isaiah 55:9
This verse highlights that God's ways are higher than human ways, but does not directly contradict Jeremiah 32:16, which is an expression of trust in God.
Isaiah 55:9: For [as] the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.
