Contradiction with 1 Kings 8:27
While Ephesians 3:19 speaks of knowing the love of Christ as something that fills us with the fullness of God, 1 Kings 8:27 questions how God can truly dwell on earth given the vastness and boundlessness of heaven and earth.
1 Kings 8:27: But will God indeed dwell on the earth? behold, the heaven and heaven of heavens cannot contain thee; how much less this house that I have builded?
Contradiction with Isaiah 40:28
Ephesians 3:19 emphasizes understanding God's love to be filled with His fullness, whereas Isaiah 40:28 highlights that God's understanding is unsearchable, suggesting that fully comprehending God is beyond human capability.
Isaiah 40:28: Hast thou not known? hast thou not heard, [that] the everlasting God, the LORD, the Creator of the ends of the earth, fainteth not, neither is weary? [there is] no searching of his understanding.
Contradiction with Romans 11:33
In contrast to Ephesians 3:19's suggestion of knowing Christ's love, Romans 11:33 marvels at the depths of God's wisdom and knowledge as being unsearchable and past finding out, implying they cannot be fully known.
Romans 11:33: O the depth of the riches both of the wisdom and knowledge of God! how unsearchable [are] his judgments, and his ways past finding out!
