Since the day we heard about you, we have not stopped praying for you and asking God to fill you with the knowledge of his will through all spiritual wisdom and understanding.

Colossians 1:9

Paul wrote these words to the Christians at Colossae, but he had never been there. Despite his lack of "in person" knowledge, he ministered effectively to the Colossians. He prayed specifically for them to better know God and his will for them. What a great idea! Let's find a mission church (inner city, overseas, hostile environment) and start praying consistently for that congregation, asking God to help them know him and his will more perfectly.
