Most of us have something we'd rather not put on the table before God—something we're holding just tightly enough that we hope He won't notice. In Luke 18, a ruler who has kept the commandments since his youth comes to Jesus asking what he still must do to inherit eternal life, and Jesus names exactly the one thing he isn't ready to hear.
There's always one thing we'd rather not put on the table when God asks us to give something up—and we usually know exactly what it is. In Luke 18, a rich man walks away from Jesus grieving because that one thing is precisely what Jesus names, and the disciples' stunned question in response—”then who can be saved?”—turns out to be our question too.
