Why did Jesus choose those teammates?

When it comes to Christian unity, Jesus points us in an odd direction by his example. When he calls His 12 closest followers, it’s not pretty: Roman collaborators, men smelling of fish, a political agitator, and a thief, among others. Many of these will never distinguish themselves beyond their denial, betrayal, and doubt of the one whom they follow. Why does Jesus make such eccentric choices? We might as well ask why Jesus wants you and me. Jesus calls whom he calls, and if we don’t all go to the same church, is that his problem or ours?
