Archbisop Oscar Romero said, "we don't follow Jesus with perfection, but the effort to follow him is what makes a true disciple."
I like that. It's trying. Which should be obvious given the obtuseness of the original 12. Though at times I think Jesus grew at bit exasperated as their denseness, he didn't replace them. He just kept trying to teach a better way.
Good advice for us. It's about the effort that makes us disciples.
