Contradiction with Matthew 21:21
This verse implies a future expectation of doubt, while John 12:15 encourages confidence and fearlessness.
Matthew 21:21: Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this [which is done] to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.
Contradiction with Luke 12:7
This verse highlights God's detailed care, which might seem to contradict John 12:15's command not to fear based on broader proclamations.
Luke 12:7: But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows.
Contradiction with James 1:6
This verse focuses on the importance of unwavering faith, contrasting with the simplicity of being unafraid in John 12:15.
James 1:6: But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed.
Contradiction with Romans 8:31
While this verse supports not fearing, it places emphasis on divine backing rather than the specific prophetic fulfillment highlighted in John 12:15.
Romans 8:31: What shall we then say to these things? If God [be] for us, who [can be] against us?
