Today, my church–Highland Baptist Church–had our Sunday School Revival today. Our pastor brought in Josh Hunt to speak. He spoke during Sunday School time, then again during church. Tonight, he is having an evening session too.
His plan is fairly simple: You find away to befriend people. You hang out with them. You become their friend them. Then, they are more likely to come to church with you. This isn't just his idea. There are scriptures in the Bible that talk about this same thing.
I Peter 4:9: Use hospitality one to another without grudging.
Romans 12:13: Distributing to the necessity of saints; given to hospitality.
