I write to encourage you to remember God is limitless. We are the ones putting limits on what God can do, or who He can use. We let fear whisper doubt in our ears. Do not minimize your potential! You have many missions, this is just one. You affect more than you even know. God has called you. I pray that he gives you the knowledge as to what is your next step.
The world is our mission field, what we decide to do with it is up to us.
