In the mid 1800s, 50,000 slaves were sold each year at Zanzibar on the coast of Africa. A church now stands where the old slave market stood. The altar is where the whipping post stood. It must be moving to visit such a church. But any church reminds us that we were once slaves — slaves to sin. Any church reminds us that the cross was worse than a whipping post, but we slaves did not go there. Christ went there, went there because He loves us, and went there because He wanted to set us free.
