Nor could John fourteen be simply further revelation, adding a pre-trib rapture to the scenario Jesus described on the Mount of Olives. The two ideas are mutually exclusive. In the Olivet Discourse, Jesus instructed the disciples to watch for the signs. These signs would occur during, and after, the tribulation. If the disciples represent the Church in John fourteen, they must also in the Olivet Discourse.
Consistency demands no less.
Those who claim to be the champions of the grammatical-historical method of interpreting Scripture cannot set aside the requirement that Scripture must first make sense in its original setting. The idea that Jesus taught His disciples about the second coming, using them as representatives of Israel and the Church indiscriminately without telling them, makes havoc of the Scriptures. This would have been incomprehensible to the disciples. Any legitimate attempt to interpret Jesus' teaching to His disciples must harmonize all of His teaching to them. The disciples still did not fully appreciate the two separate advents of Christ.
