The episode on the road to Emmaus (Luke 24:13-36) is beautiful to me because it is so instructive.
Just a week before, these two men believed they had found in Jesus the answer to all their political and spiritual questions. But their hopes that He would "redeem Israel" had been dashed. They were confused and disappointed followers of Jesus. (Don't know about you, but I've been there and done that.)
But Jesus specifically and intentionally went to them in their struggle. (And He finds me in mine.)
After walking with them for awhile He started to leave them with only a partial understanding. They asked for more teaching and He obliged. (He gives me more when I ask.)
In verse 27 Jesus used the scriptures to teach about himself. What Scriptures? The Old Testament, because that is all they had.
I would love to have been there and heard Jesus tell about himself and his relationship to those Old Testament writers. He could have said "I know exactly what Isaiah and David meant because I was right there with them when they wrote those words." That is really teaching with authority..." (Mark 1:22)
And then they went and told others.
