Verse 6>Now he said this, not because he cared about the poor [for he had never cared about them], but because he was a thief; and since he had the money box [serving as treasurer for the twelve disciples], he used to pilfer what was put into it.

In this verse I have seen that Judas never had good intentions,perhaps he said it so that Jesus will think he was caring. That's a lesson to us that not all the people that shows care to us actually mean it. So be wise.
Have you seen it with me that Judas was a thief even when working with Jesus,so it's possible that someone can be in church but yet a thief, witch, an adulterous man or woman etc. We have to be vigilant, not because a brother is in the choir that makes him born again. May God help us.

verse 18>For this reason the crowd went to meet Him, because they heard that He had performed this [miraculous] sign

In this verse we saw that the people never followed Jesus because of anything but because of the miracle he performed by raising Lazarus from the dead, that shows what is going on in our world today people go to church because the presiding pastor does miracles, they don't go to meet God, or to have an encounter with God, may God help us not to follow people because of what they have to offer us, but b genuine, having good motives.
