‘Vision-casting’ must only be accomplished if the one casting the vision has received his instruction from God. Every time a vision is cast in the Bible the vision has come from God and there are many, many examples, “Now there was a disciple at Damascus named Ananias; and the Lord said to him in a vision, “Ananias.” And he said, “Here I am, Lord.” And the Lord said to him, “Get up and go to the street called Straight, and inquire at the house of Judas for a man from Tarsus named Saul, for he is praying, and he has seen in a vision a man named Ananias come in and lay his hands on him, so that he might regain his sight.” But Ananias answered, “Lord, I have heard from many about this man, how much harm he did to Your saints at Jerusalem; and here he has authority from the chief priests to bind all who call on Your name.” But the Lord said to him, “Go, for he is a chosen instrument of Mine, to bear My name before the Gentiles and kings and the sons of Israel; for I will show him how much he must suffer for My name’s sake.” Acts 9:10-16 NASB.
In the OT we find that Nehemiah was charged with the task of rebuilding the wall around the city of Jerusalem after being in ruins for more than one hundred years. However, what we must take into account is the prayer time that this man of God utilized. Nehemiah’s vision came after 4 months of prayer before approaching Artaxerxes and his presentation changed the attitude of the Jews living in Jerusalem. Read Nehemiah chapters 1 and 2. “Then I said to them, “You see the bad situation we are in, that Jerusalem is desolate and its gates burned by fire. Come, let us rebuild the wall of Jerusalem so that we will no longer be a reproach.” I told them how the hand of my God had been favorable to me and also about the king’s words which he had spoken to me. Then they said, “Let us arise and build.” So they put their hands to the good work.” Nehemiah 2:17-18.
Yes, ‘vision-casting’ is biblical, but in my opinion this must not be attempted by one person alone. If and when a pastor feels that God is leading him to do something ‘in God’s Name’ he should first go to some spiritually-discerning men. But, look at these words of Jesus, “Truly I say to you, whatever you bind on earth shall have been bound in heaven; and whatever you loose on earth shall have been loosed in heaven. Again I say to you, that if two of you agree on earth about anything that they may ask, it shall be done for them by My Father who is in heaven. For where two or three have gathered together in My name, I am there in their midst.” Matthew 18:18-20. (Please read the verses prior to these.) “Why did Jesus say this?” It just seems reasonable not to do things without clear direction from the Father.
Jesus is Lord.
