If we really believe what we claim to believe then we should have a burden for souls. There are many who will attend church meetings but not the regular weekly prayer meeting. If they had a real burden for souls, they would be praying regular in the unspectacular regular prayer meeting. The supreme test of someone’s burden for souls is prayer. As we realize this is a problem only God can deal with, it drives us to our knees.
