Dare You To Move.

If the Lord has placed a calling on your heart he will enable you to do it wherever you are. The calling is not dependent on the strength and resources of those who are called, but the one who calls. It’s not a waiting game. Don't wait to be completely prepared and perfected (according to your own standards.)
Jesus repeatedly spoke of being willing to forsake all things immediately, no waiting. Do it now.
When he calls you, immediate is the appropriate frame of time to respond. No turning back to tie up loose ends. No final farewells to the familiar. Cut loose and go.
Have you recognized a calling and burden in your heart that the Holy Spirit has been speaking to you?
Why have you not done what you have been moved to do?
Clinging to the familiar for strength turns quickly to shackles that chain us and keep us from growth and achieving the purposes the Lord has for us.
Sometimes, we need adjustment to our own vision. You may not even need to leave where you are. The things the Lord calls us to do might be accomplished in your current location and community; touching the people around you now. So often we're waiting for some grand opportunity or distinctly huge voice to move us. Sometimes the Lord does work like that, but sometimes He wants to use you where you are. If you have a burden, but have yet to receive a calling to somewhere out in the great blue yonder, look around you for ways the Lord can fulfill that calling right now!
