I address their questions here. If that is the correct reading, then John's rewards are not specifically in question. Only the rewards of the readers would be clearly in question. That is not, however, the reading of most Greek manuscripts. In addition to the manuscript evidence, the context favors the first person plural reading as well.
All manuscripts read the first person plural there.
The three-fold use of we in v 8 seems much more natural than an unnecessary switching back and forth from you to we to you . The Greek word used here for reward is misthos . However, it is normally used in the NT to refer specifically to eternal rewards which believers will receive for work done. It is extremely telling that all the other uses clearly refer to eternal rewards. No, it is not likely that misthos here refers to current rewards.
