Many people do fire and brimstone preaching and people can get apprehensive to the gospel. A yelling man isn't recieve very well unless he is a soldier doing his duty or in a parade.
I suggest setting up as a worship band or a show. Like a radio booth. Or preform some act like a gospel skit. It is said when 2 or 3 are gathered in my name there am I among them. Its better to do something that earns money that the cops don't mind.
Have a magic show or gospel cube that can help you witness. Play a game with them or serve them in some way. A hot meal gets people to see your kind. Look for ways to witness hand out tracts.
Apologetics help. Take a book like reason for God or a systematic theology. Remember this do everything in your relationship and with the voice of the Lord. Look for witnessing tools and sell them on the street. I may look up some and put them on the blog.
Don't be apprehensive, threatening or mean. The point is for them to find Jesus. Deliverance works when you understand wisdom. Prayer and free hugs work well.
Prayer and common sense.
Write and blog, maybe do a journal or two make content, take some exegesis and hermenuetics of the Bible. Setup yourself in a way that build expertise and respect. Do a parade for the gospel, people like those. Its important to make God look good set a good example. Be cool and wise. Don't be arrogant or intimidating. Be fun, bubbly and righteous, remember your a stranger. So treat them wrong and they'll be apprehensive. I want you to treat them well and show them relationship with Jesus. Make a friend make group on Facebook and show them the character of God. Not the devil's misperceptions.
