Mark Chapter 14

Mk.14:51 A young man, wearing nothing but a linen garment, was following Jesus. When they seized him,
Mk.14:52 he fled naked, leaving his garment behind.

When I read these two verses I was quite curious about this man.
First: Who was this man??
Second: Why did he only wear a linen garment? (I mean, it is not common to wear nothing but a garment)
Nevertheless we still can see, that he had the will to follow Jesus. That is already one point in which he was better than the disciples, but as they seized him, he still fled. So in the end he was not better than the rest of the disciples, because he fled (and he fled naked- we can say that he really ran for his life, his skin and his bones (Haut und Knochen)).
If someone runs for his life, then he is able to run faster, then ever before. So if we run for our spiritual life (as Paul says "I have finished the race"(2.Timothy4,7) => we should also run this race) we should never forget to run as fast, as we would if we ran for our physical life!!
