Is It Important for Philadelphians to Practice What They Preach?

Philadelphians are promised an open door (Revelation 3:7-8).  The context and other scripture seem to indicate that this is an open door for preaching the gospel to the world.  Church history, with Herbert W. Armstrong, also seems to confirm that the open door promised to Philadelphians refers to the gospel.

So Philadelphians are to preach the gospel.

But should Philadelphians practice what they preach?  Is that important to God?  To have that open door, to have it wide open, and to walk through that door, is it a requirement that the Church practice what it preaches to the public?  Or will God give us a wide open door even if we preach one thing to the public but do something else ourselves?  If we have a double standard, will God give us a wide open door to preach what we ourselves do not practice?

In this post, I am only asking the question.  Let the reader think about it.  Let each of us examine ourselves, as I examine myself, with this question in mind.  Are we willing to do what we ask others to do when we preach the gospel and the Ezekiel warning to the public?

This question relating to self-examination perhaps belongs during the time of the days of unleavened bread.  But I can't wait.
