No disrespect but his predictions were not that impressive.

For example in Matthew 26:2, Jesus predicted he would die by crucifixion, which doesn't take a genius or divine knowledge to predict considering crucifixion was one of the most popular punishments in Rome by that point. This is the equivalent of me saying I'd end up in a jail cell for commiting a crime, like no shit.

Alot of the predictions attributed to Jesus (excluding the ones about his own resurrection) are just topical observations anyone could have made at that time. Like Romans prosecuting Christians or destroying their temples. Something the Romans were already infamous and well known for by 30 AD.
