Contradiction with Isaiah 63:3
This verse describes the Lord treading the winepress alone, which differs from the angel wielding the sickle in Revelation 14:19.
Isaiah 63:3: I have trodden the winepress alone; and of the people [there was] none with me: for I will tread them in mine anger, and trample them in my fury; and their blood shall be sprinkled upon my garments, and I will stain all my raiment.
Contradiction with Matthew 13:30
This verse speaks about letting both the wheat and tares grow until harvest, wherein angels gather, which is contrary to the immediate reaping of grapes in Revelation 14:19.
Matthew 13:30: Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.
Contradiction with Joel 3:13
It speaks of harvesting because the harvest is ripe, which is contradictory to Revelation 14:19 where the grapes are fully ripe and pressed in wrath.
Joel 3:13: Put ye in the sickle, for the harvest is ripe: come, get you down; for the press is full, the fats overflow; for their wickedness [is] great.
Contradiction with Revelation 19:15
This verse attributes the treading of the winepress to Christ, differing from the angel performing it in Revelation 14:19.
Revelation 19:15: And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
Paradox #1
The contradiction or conflict might arise from the imagery of divine wrath and judgment. Some people could find it difficult to reconcile the idea of a loving and merciful God with the depiction of destructive judgment. This tension between mercy and justice might seem inconsistent to some readers who struggle to understand how both can coexist.
