Yes this is the argument that one of the false teachers that I am debating with is making. I have found plenty of internal evidence especially in the last chapter that John wrote it, and even some church fathers agreed that he wrote it. But this false teacher turns and gives me some views of these liberal bible scholars that say John did not write the 4th gospel. I lack a good exegetical commentary on John (have one by RC Sproul but he is more of a theologian) so I am turning to my textbook on NTI by DA Carson and Moo whom are fine Bible scholars. So Greek Tim and others what can I say? Thanks..
