I'm afraid many churches and Christian ministries have become nurseries. Intending to show mercy and grace, we've instead coddled, rocked and nursed new believers way past their infancy. They've needed hand-holding and we've been eager to comply.
But maybe we should be boot camps instead of nurseries. When they leave boot camp, they've toughened up and know the basics in handling a gun, surviving impossible terrain, and how to storm a beachhead. They know they have an enemy who wants to destroy them.
