My father first locked eyes on my mother at a party in London. Next he gate-crashed a second party, then organized a third, just to see her again. Finally he asked Mum out for a country drive, picking her up in his old Rover sedan—his treasured possession.

Mum and Dad became sweethearts, but there was a problem. Mum was about to move to Peru to become a missionary. Dad took her to the airport, then five months later arrived in Peru himself—to propose to her. And the best part of the story? He’d sold his beloved Rover to pay for the plane ticket.

If you would’ve asked Mary, the sister of Martha and Lazarus, what her most treasured possession was, she’d have shown you a precious bottle of “expensive perfume” (John 12:3). And if you’d have been at the party she and Martha threw for Jesus (v. 2) and watched her lavish that bottle’s contents on his feet, you’d have known just what Christ meant to her. He was that precious, that valuable.

For my mother, Dad selling his car wasn’t just about a plane ticket. It was a sign of how much he valued her. And Mary’s actions had deeper meaning too—she was preparing Jesus for His burial (v. 7). Like her, when we sacrifice for God what we treasure most, we take part in His redemptive work by echoing His great sacrifice for us.
