The church will prevail

Gregory Elder writes:
Growing up on the Atlantic Coast, I spent long hours working on intricate sand castles; whole cities would appear beneath my hands.
One year, for several days in a row, I was accosted by bullies who smashed my creations. Finally I tried an experiment: I placed cinder blocks, rocks, and chunks of concrete in the base of my castles. Then I built the sand kingdoms on top of the rocks.
When the local toughs appeared (and I disappeared), their bare feet suddenly met their match.
Many people see the church in grave peril from a variety of dangers: secularism, politics, heresies, or plain old sin. They forget that the church is built upon a Rock (Matt. 16:16), over which the gates of hell itself shall not prevail.
