I imagine two main objections to premise 1.
The disciples did not sincerely believe in Jesus and endured persecution because:
The disciples wanted fame.
The disciples were delusional.
I would appreciate feedback and other objections.
The third objection you’ve neglected was that the disciples were on a secret mission, as the churches have accepted some, such as the prophets, are sent by God. Their secret purpose would have been to push humanity forward by a kind of manipulation, acting better than men while in the disguise of men. There is a lot of unexamined evidence that such figures existed throughout world history, unearthed through careful study of them.
Of course to have noticed this third alternative would demarcate you as either another hidden messenger, or as a man recognizing he has been manipulated by a higher power. But now that I’ve brought it up, if you deny it then it is certain you are a man and have brought no new insights from the Deity intended for humans like the prophets used to do.
Your whole argument falls quickly if I merely ask what you mean by “eternal life with God.” You are allowed to say that with virtually no meaning because everyone else has been doing so. Swedenborg pointed out the human notion of Heaven doesn’t rise high enough to be called an idea, but this remark has been overlooked although it overturns the whole religion. This is going beyond Jesus, who actually was invoking greed when He offered a tradeoff, promising Heaven for proselytizing activities rather than actual virtue.
OK, number one, if you want to be with Jesus, do you think that He is a family man? If you do then you are denying His strong words, that those who do not deny their kin are not worthy of Him! Being with Jesus means moving outside the family for your meaning. Yet the entire human realm revolves around the family, no other options having shown.
Number two, do you think Jesus will exchange money with you? If you think so you haven’t begun to understand His parables, that underscore no one can take wealth into Heaven. So if Jesus won’t exchange money, that means if He is going to eat you’re going to have to work to make it so, and Jesus will also be working so that you can eat, as He showed by washing the feet of the disciples. Yet everywhere in this world money reigns.
You can only be with Jesus by being like Jesus, but I expect you are like the wealthy man who asked what he must do, and Jesus said, “Go, sell what you own,” and he refused. Christians moan continuously about being with the Lord, while continuing to hate and compete against the neighbor. They think God is fooled by prayers and hymns; He is not.
