2 John is one of the shortest books in the Bible, but its repeated themes from 1 John really reinforce the struggle that the earliest Christians faced: who Jesus was. It probably became somewhat fashionable to come up with an alternate version of Christianity, especially one that might have been easier to understand than the Jesus that has come to be understood through the centuries. Don't take the easy road, though. Knowing Jesus is knowing the process of formation, and that means allowing our understanding to be changed.
