I don't usually do the biblical bits here, but this one tickled me:
1. Jesus calls himself the Son of man (e.g. Matthew 16:24-28):
Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.
For whosoever will save his life shall lose it: and whosoever will lose his life for my sake shall find it.
For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?
For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.
Verily I say unto you, There be some standing here, which shall not taste of death, till they see the Son of man coming in his kingdom.
2. Numbers (23:19) points out that he's therefore NOT God:
God is not a man, that he should lie; neither the son of man, that he should repent
