It isn't that we should run away from persecution, but that we must discern between when someone is hearing the message and when the swine are gathering. We are told not to cast our pearly before swine, and the message doesn't end there. Jesus goes on to say that swine tend to turn on you and devour you if you hang around them too long unless you are going to give them what they want. Here's a hint: They don't want you to stay clean, nor do they want to eat of the fruit of righteousness.
I also don't believe that we are to pick and choose who is worthy of the Gospel by our own standards. Surely, all means all, and we are to go into the world and preach to all God's creatures, fulfilling the command of Christ Jesus our Lord, the example we emulate in preaching the good news. We are to preach to all, but when one is met with hatred and reviling, should we continue at length to debate with one who is surely set in their ways and pridefully so? Should we share with all, but spend our time more wisely, with those who are willing to have a discussion instead of a debate? There is a lot more to this topic, and I hope to start a discussion here. The comments section below is fine for conversation, and the linked thread on Facebook is a fine place to talk this over also.
