I've seen a lot of various open air preachers. One thing I have observed is that many of them become very hardened in the face of constant adversity. It's obvious that there are many people possessed by devils and one of the strategies of those devils is to constantly bombard them with evil to cause the preachers to hate the people that are captive and to recompense evil for evil causing them to leave off preaching the truth in love being led of God and get them preaching by their own power, in the flesh to be void of the power of the Spirit of Christ.
I'm a firm believer that anyone that thinks they are called to preach in this manner, should first, be certain that this is what their calling is of God and be sure to spend much time in the secret place of the Most High. It also helps to have others supporting them in prayer before, during and after these events.
I've seen these street preachers before:
https://youtu.be/j1gD7x0O9sAI wonder if there's anyone here that's seen their preaching also. They've traveled throughout the entire nation for over a decade having preached at many hundreds of events and millions of people. Most of their preaching is on the western side of the country though. They seem to have a very solid message and as the years go by they kind of teeter back and forth with becoming jaded and hateful and going back to having a genuine concern for their audience.
So I think that they are genuinely called to do what they do and would ask anyone here to remember them in your prayers that they would not be effected by the world or the strategies of the devils.
I have never done this kind of open air preaching before. So I do not know the battles that they face firsthand beyond the revelation given to me in prayer and their testimonies.
How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth!
