Sacrifice is hitting a point where you see your own limits, and give beyond that. It’s saying to God, “Fine, let my life make no sense at all, let it be a failure, let it be wasted, but above all, let it be yours.” It’s throwing yourself out across a canyon you could never leap across, trusting somehow there will be a parachute, or a net, or a bridge, or somehow it will be OK—even somehow better—because of your leap. It’s knowing this: God is in charge. Period.
