If the Lord has called you, you must not doubt, you must continue the path of vision, even when obstacles arise, you must walk far and wide, so that fears disappear.
God's calling is one of the greatest calling any man will pray to get, because when God calls you he will use you to do great and mighty things for his church.
We must not resist, we must be obedient, and make that perfect vision transformed into joy fulfilled for the Lord. He calls us with a purpose, he knows we are capable of fulfilling his mandates.
