Men who stand on any other foundation than the rock Christ Jesus are like birds that build in trees by the side of rivers. The bird sings in the branches, and the river sings below, but all the while the waters are undermining the soil about the roots, till, in some unsuspected hour, the tree falls with a crash into the stream; and then its nest is sunk, its home is gone, and the bird is a wanderer.
