I sometimes think the Lord gave us the experience with Rosa and starting church in the projects because it so closely parallels Luke 10.
In Luke 10:1, Jesus commissions 72 disciples to go ahead of him in pairs to all the towns and places he plans to visit. Jesus had a strategy for the area–the disciples had to listen to his instructions, go where he told them and he would follow.
Jesus told me very specifically which street to walk because he planned to visit Springfield. My job was to hear him and obey.
The ability to hear God's voice is vital if we are going to be on mission with God. He has plans for the area where you live. As you listen to him, he will give you a place to pray for, or put a person on your heart. Maybe he will say to you, "Get chatting with the person next to you in the grocery line–she needs to hear from me today." Or maybe he will put a people group on your heart–you will find yourself with an unaccountable burden to pray for skateboarders, or students, or the elderly.
If Jesus sends us somewhere, it's because he plans to come with us. You change your job? Jesus wants to do something in your new place of work. You move house? What does Jesus want to do in your new neighborhood?
