What Does God Mean By Unhindered?

And he stayed two full years in his own rented quarters and was welcoming all who came to him, preaching the kingdom of God and teaching concerning the Lord Jesus Christ with all openness, unhindered. (Acts 28:30-31 NASB)

The setting is Paul in Rome, finally.  Shipwrecked on Malta after a huge storm drove him, his guards, and his companions all the way across the Mediterranean Sea, he makes it to Rome after serious hardship and danger.  He has met with the leading Jews who had not received any word or person concerning him from Judea, and they have heard the gospel and were in disagreement over it.  Now Paul stays in his lodging with a guard present at all times.  He didn't go out to the synagogue, they came to him.  He doesn't go out to meet others, he welcomes all who come to him.  He preaches and teaches, but from his lodging, and does so for two whole years.  Yet, as the NASB faithfully translates, the book of Acts ends with the word, "unhindered".

I have to wonder what God means by "unhindered" under these conditions.  The chains aren't a hindrance.  The storm on the way isn't/wasn't a hindrance.  The shipwreck wasn't a hindrance, the lodging with a soldier isn't a hindrance, and so also not leaving his quarters for two years.  These aren't hindrances.

Maybe I need a better understanding of hindrance, because I think of the word meaning "to make an activity more difficult" rather than actually "to cause an activity to stop".  To me it has more to do with "influence" than "control".  Well, if you believe as I have, we could both use a short lesson.  The word "hinder" has both ideas, to influence and control, because it refers to the attempt to control which may succeed (and therefore mean to control) or fail, perhaps for a time (and therefore mean to influence).

But to be unhindered would mean to be free from attempts to cause him to stop preaching.  At least the choice of this word in English carries that meaning.  The word in Greek which Luke used is akolytos which is only used here in all of the Christian Scriptures.  It's a compound word made up of the negative particle, and the word "to hinder".  The word, "to hinder", has the nuance of forbid as it's used in the Christian Scriptures.  So, to negate that would mean that Paul wasn't forbidden from preaching and teaching.

I suppose the point I'm walking around but not pulling out directly is that, to my Master, things that make something difficult for me do not mean that He doesn't want me to do it.  Just because a thing may have all sorts of obstacles does not mean it's the thing from which my Master is keeping me.  It could be that these obstacles are part of the blessing in His call or design for me. 

Even so, could it also be that what is "unhindered" isn't Paul at all, but the things preached and taught?  And so you get what I mean, consider that we are looking at such a preaching and teaching, and Paul is now dead.  That would seem the biggest hindrance of all, and yet here we are.  Perhaps what my Master meant by what He inspired Luke to record is that no obvious obstacles can hinder the Master of the universe from His purpose; not even the Emperor of Rome.  That is very reassuring to me.
