Our life and activities on earth is connected to the keys of the Kingdom of Heaven. He has given keys to unlock doors which were once closed. God has set before us an open door, so don’t go around looking for another door. Step in and walk through the open door and allow God to work through you by giving Him free access and unrestricted admission. The only thing that will limit the effectiveness of an open door will be our lack of faith, not God’s unwillingness.
