When the promise is not yet visible, what a person keeps in view is the whole difference between endurance and collapse.
A gap between what was promised and what can be verified breaks most people, and it breaks them through their eyes. Attention held on the missing evidence enlarges the missing evidence, the enlargement produces discouragement, and discouragement produces quitting long before anything had time to arrive. The move available is to aim at something equally real that can be seen today.
Jesus crowned by way of the dying, rather than spared it, is the one piece of evidence already visible, and whatever is held in view becomes the operative reality, setting the state a person waits inside. The sight was given by grace rather than achieved by staring harder. None of this shortens the wait; it decides whether a person is still standing when the wait ends.
