Moving forward toward what God has for you, or for your group, will introduce you to serious conflicts. Blood will be bled, and tears will be shed. But that's still better than rebelliously marching around in a pointless circle for forty years.
An invisible goal-line might as well not exist. If it's impossible for a normal mortal to tell if you have reached your goal, then you don't really have a goal.
Setting improbably grand goals makes people cynical about goal-setting, which is bad.
We can't just make up goals, then talk and act like attaining them is a sure thing. Even great goals fall under the "If it be Your will" rule. It isn't bad leadership to be modest before the face of God.
A goal without a workable plan to get there is just another name for wishful thinking.
