This picture was taken a few years after the death of Walther (published in 80 Eventful Years, page 102).  Pieper was chosen to be on the faculty when he was 26, and became it's President when he was 35.  Pieper was a young man among older men, yet he was their leader.  Pieper was a spiritual leader, leading the way with pure Christian doctrine, working for agreement with other church bodies and attempting to correct their un-Scriptural errors so that they too might know the truth.

And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions...  Acts 2:17
