"I think the number one obstacle preventing you and I from stepping into Jesus’ call is this sense that we’re not worthy of being disciples, that we don’t meet the requirements... The story of Levi blows all that up. Because it insists that there are no qualifications for following Jesus, that the only prerequisites for our becoming disciples have already been met by Jesus, that he has taken our shame on himself so that we can take on his calling, that he has traded our vocation for his own."
