Contradiction with Matthew 5:14
This verse describes followers of Christ as the light of the world, implying that their light should shine universally and openly, while Mark 4:21 suggests the concept of hiding a light under a bushel is absurd, implying it should always be exposed.
Matthew 5:14: Ye are the light of the world. A city that is set on an hill cannot be hid.
Contradiction with John 3:19
This verse states that people love darkness rather than light due to their evil deeds, which could contradict the notion in Mark 4:21 that light is meant to be revealed and not hidden.
John 3:19: And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
Contradiction with Luke 12:2
This verse claims that nothing is covered that won't be revealed, contrasting with Mark 4:21's rhetorical question which hints that light needs deliberate exposure.
Luke 12:2: For there is nothing covered, that shall not be revealed; neither hid, that shall not be known.
Contradiction with Matthew 13:44
This verse speaks of hiding a valuable treasure in a field, contrasting with the idea of not concealing light in Mark 4:21.
Matthew 13:44: Again, the kingdom of heaven is like unto treasure hid in a field; the which when a man hath found, he hideth, and for joy thereof goeth and selleth all that he hath, and buyeth that field.
