It seems hard to believe he intended some of these titles to apply to the Logos only after his incarnation. Rather they express the eternal characteristic glories of his loving interventions among all people. Any person at any time and in any place could experience the Son in one or more of these ways. If this is what John had in mind, it puts every human being everywhere and at all times in a faith or light rejecting situation. In this model faith is not a cerebral decision based on sufficient information.
Little children are naturally responsive to light and love.
As are retarded persons. We can also believe that the light of the eternal Son of God can be responded to by people whose ideas about God, and religion, are very faulty. Why then do we need to take the good news to all people's of he world. This means we don't have to believe that everyone is condemned to hell before our missionaries arrive on the scene. But the Son certainly wants people everywhere to learn how the love of God works.
