Contradiction with 1 Corinthians 3:6
While Luke 8:5 discusses a seed being sown without mention of growth, 1 Corinthians 3:6 suggests growth as a necessary step after planting.
1 Corinthians 3:6: I have planted, Apollos watered; but God gave the increase.
Contradiction with Matthew 13:25
Luke 8:5 describes the seed being devoured immediately, whereas Matthew 13:25 shows a scenario where the seed grows until an enemy sabotages it.
Matthew 13:25: But while men slept, his enemy came and sowed tares among the wheat, and went his way.
Contradiction with John 15:2
Luke 8:5 implies no growth due to devouring, but John 15:2 discusses pruning branches that have some growth but do not bear fruit.
John 15:2: Every branch in me that beareth not fruit he taketh away: and every [branch] that beareth fruit, he purgeth it, that it may bring forth more fruit.
Contradiction with Galatians 6:9
Luke 8:5 indicates an immediate loss of the seed, whereas Galatians 6:9 encourages persistence in doing good for eventual results, implying delayed outcomes.
Galatians 6:9: And let us not be weary in well doing: for in due season we shall reap, if we faint not.
Contradiction with Matthew 7:17
While Luke 8:5 shows no fruitful outcome, Matthew 7:17 contrasts this by indicating that every good tree bears fruit, assuming growth occurs.
Matthew 7:17: Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
