I live on an island.
Our topsoil is one inch deep, so I know lots about sand.
But it wasn’t until this past Sunday that I
understood the sand referred to in the hymn,
The Solid Rock or, as originally titled:
The Immutable Basis of a Sinner’s Hope.
I had always pictured ‘sinking sand’
as being like beach sand. Slippery, pulling out from under your feet
by the waves:
Or giving way, like the side of a dune:
Like at Dionis, where you always have to slide down or jump.
The hymnist’s sinking sand is more like this:
On Christ the solid rock I stand
All other ground is sinking sand,
all other ground is sinking sand.
