> John 17:12 While I was with them in the world, I kept them in thy name: those that thou gavest me I have kept, and none of them is lost, but the son of perdition; that the scripture might be fulfilled. (Also John 13:21, 25-27)

> Matt. 26:56 But all this was done, that the scriptures of the prophets might be fulfilled. Then all the disciples forsook him, and fled.

The alleged problem is that Jesus supposedly "lost" some sheep in the second set of verses. However, the first two verses do not contradict the third, as Judas had removed himself from the flock through his own free will, making him "the son of perdition." John 18:9 and 17:12 complement each other, with the former being informed by the latter. Furthermore, Matthew 26:56 refers to the disciples scattering in fear, not being eternally lost, so it has no bearing on the permanent loss discussed in the Johannine passages.
