"These all died in faith, not having received the things promised, but having seen them and greeted them from afar" (Heb 11:13)
What a great image (... and not just the still from Lawrence of Arabia)!
I think that helps with progressive revelation. They didn't trust the shadows, but the person of Christ who was to come. Nevertheless, he hadn't arrived and they couldn't see him as clearly as we can. Also, on an emotional level, "greeting from afar" implies they were full of joy to see Jesus on the horizon and welcomed him.
