The Bible instructs us to write the vision and make it plain. There is a promise contained in the Scriptures declaring that a vision is for an appointed time and will surely come to those who obey the Word of God.
I have found that the Old Testament Patriarchs like Moses, David and Elisha recorded their calling and visions on their rod. It is also confirmed in the New Testament that Jesus commanded the disciples to leave everything behind, but to take their rod, or their vision, with them.
