			If God knew all we could be is miserable judges, why would he say that we will judge angels and tell us to judge ourselves and even others under certain conditions? He must have more confidence in our abilities than we do some times.
		
		
	 
I think you're missing the point completely, the NT and particularly Jesus is trying to tell us not to judge at all. The point of telling you to judge yourself is to get you to see you have faults also. It boils down to what gives us any right to judge anyone while we ourselves are not without fault. Rmember, it was not your righteousness but the rightenouss of Christ that you made you pure...
Read Jesus' teaching carefully;
Matthew 7:1 
Judge not, that ye be not judged. 
He is saying don't judge anybody because you yourself can't stand up to judgement.
2 
For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. 
Again, he says keep this in mind, what ever stick you use to judge your fellowman will be used to judge you also. Don't consider that stick to be a drinking stick and because you don't drink you're ok, the stick only says SIN. And all have sinned and come short of his glory... You say you didn't sin and you call God a liar.
3 And why beholdest thou the mote that is in thy brother's eye, but considerest not the beam that is in thine own eye?
How do you see the sin's of your brother while you yourself have sin in you? 
4 Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? 
5 Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother's eye. 
6 Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you. 
I think you get my point, now let's look at Jesus use this principle in practicle application;
John 8:4 They say unto him, Master, 
this woman was taken in adultery, in the very act. 
5 Now Moses in the 
law commanded us, that 
such should be stoned: but 
what sayest thou? 
6 This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not. 
7 So when they continued asking him, he lifted up himself, and said unto them,
 He that is without sin among you, let him first cast a stone at her. 
8 And again he stooped down, and wrote on the ground. 
9 And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst. 
10 When Jesus had lifted up himself, and saw none but the woman, he said unto her, Woman, where are those thine accusers? hath no man condemned thee? 
11 She said, No man, Lord. And Jesus said unto her, Neither do I condemn thee: go, and sin no more. 
Notice Jesus never said she was not without sin. In fact, he tells her not to sin any more so he acknowledges she did sin. However, he says the only way you ought to judge her is if you yourself is without sin. So you if you have no sin, cast the first rock. No one could cast a stone because noone could measure up to not having sin.
