This week there are a couple of options for preachers.
One can preach on the Ascension on Thursday or Sunday:
Luke 24:36-48 (Why Jesus Ascension was actually necessary for his ministry)
Acts 1:1-11 (First Lutheran Church of Jerusalem)
Then there are the regular lectionary passages for Sunday
John 17:20-26 (Jesus prayer for his disciples
I play around a bit with the idea of God's purposes for creation and humanity.
Acts 16:16-34 (Jailed in Philippi)
Simply a powerful story with great preaching potential.
For those working with the narrative lectionary I have, at best, some scratch notes on Corinthians 15 that need some serious updating!
