2 John 8

sn The things we have worked for probably refers to the pastoral and missionary efforts undertaken by the recipients of the letter in their own community and surrounding communities. This work would be “lost” if the opponents with their false teaching are allowed to proselytize unopposed.

sn The idea of a reward for Christians who serve faithfully is not common in the Johannine writings, but can be found in Rev 11:18 and 22:12.
