Where the gospel is preached isn’t as important as WHAT is preached. It must be truth...as taught in the Bible. Anyone can preach the Word anywhere. “Where two are more are gathered in My name, there I shall be also”...said Jesus. Matt. 18:20.
Filling young minds with “pablum” doesn’t give them anything to grasp and it becomes meaningless.
Aw shucks! I thought it was the colored sailor told to preach to the sharks and stop “de smackin’ o’ de lips” as they ate a whale.
