Prayer Evangelism is a chain reaction. It begins with blessing. Blessing opens the door to fellowship. Fellowship creates an atmosphere to minister to felt needs. When you minister to someones felt needs and God shows up, now they want you to explain to them why, so you proclaim the good news.
Bless> Fellowship>> Minister>>> Proclaim
You get more out at the end than you put in at the beginning.
Watch this cool video to see how one tiny little domino can start a chain reaction that releases 10 billion times the energy at the end.
