Acts 31

The end of Acts actually really confused me the first time I read it. I wanted to know what happened to Paul but ended up reading through the rest of the letters in the New Testament without finding out. The last verses of Acts are just:

30 He lived there two whole years at his own expense, [11] and welcomed all who came to him, 31 proclaiming the kingdom of God and teaching about the Lord Jesus Christ with all boldness and without hindrance.

I wonder why Luke (inspired by the Holy Spirit) chose to end Acts this way. Maybe he wanted to reflect on the importance of Paul's life, rather than the fact of his death. Probably it's how Paul wanted to be remembered, preaching the gospel right up until the end.
