Jesus asks in our Gospel reading today (Mk 4:21-25) the rhetorical question about one putting a lamp under a bushel basket or under a bed rather than on a lampstand. Of course you put a lamp on a lampstand so it casts its light further. And what comes about in the light, things that are hidden in the dark are revealed.
We believe Jesus is the light of the world. In that case, was Jesus referring to himself, that his mission wasn't to be hidden, but to be set up high to shine light in our darkness. And if so, does that make his cross a lampstand?
