Final answer:
False prophets will perform signs and wonders to mislead followers of Jesus. A modern analogy for Roman gladiators is football players, as both serve as entertainers for public spectacles.
Step-by-step explanation:
According to biblical accounts, specifically the New Testament, false prophets will perform signs and wonders in order to mislead the followers of Jesus. This warning is given to believers to be vigilant and discerning of those who come in God's name but are actually deceivers.
Regarding the modern analogy for the Roman gladiators, a likely comparison would be with football players. The gladiators were entertainers who showcased their skills in combat within an arena, and although much more violent and life-threatening than modern sports, the gladiatorial games were a form of public spectacle, similar to the way today's society watches football games as a form of entertainment.
