Contradiction with John 3:8
Luke 7:24 depicts organized, purposeful communication about John the Baptist, whereas John 3:8 speaks of the mysterious and unpredictable nature of the Spirit's guidance.
John 3:8: The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
Contradiction with James 1:17
Luke 7:24 highlights the changeability of human messengers and missions, in contrast to James 1:17, which speaks of God's unchanging nature.
James 1:17: Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
