We are not exempt from the task of believing God. However, God is faithful to fulfill His word and He honors tenacious faith. The last component of vision is prayer. However, many of us treat prayer as if it were the weapon of last resort. To be truthful, however, prayer is not a weapon.
Prayer is the battlefield.
We must not overlook the fact that we have an enemy who is determined to thwart God's vision at any cost. If the vision is to be fulfilled, we must be committed to wage spiritual warfare. For the saint, that warfare is best fought on our knees. The Bible gives us some great promises in this regard. Churches with Vision Healthy churches are churches that put those components into place.
