Stay at the Temple

Luke 24:53 And they stayed continually at the temple, praising God.

This is the last sentence writen by Luke in his gospel. Why is this meaningful?

Let's notice how the gospel of Luke starts
Luke 1:1 Many have undertaken to draw up an account of the things that have been fulfilledamong us, 2 just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. 3 With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account for you, most excellent Theophilus, 4 so that you may know the certainty of the things you have been taught.
