@Sam81:
If and when the day comes I will street preach someday (under proper preparation for it - Heavy prayer, fasting, and research on street preaching), I will do things a little differently than your average street preacher. If you have ever watched street preachers on YouTube you will notice that many of them get into arguments (call certain people devil's or how they are not of God, etc.). But I would tell them to accept the love of Jesus and how He will change their life. I would focus on the love of Jesus and what He went through for us. I would focus on how He was whipped and beaten for them. How He loved them so much to suffer for them and die for them so as to pay the price for their sin so as to offer them the free gift of salvation to forgive them and to help them to walk uprightly in His love. I would use images of love and not hate to draw them close to Jesus. Yet, I would say they need to seek the Lord's forgiveness. I will say to them that grievous sin can separate them from God. But I would do so in love. For Jesus loves them so very, very, very much. I would shout to them that Jesus loves them. I have severe ringing in the ears, so if a person wished to say something to me, they would have to either speak very loudly or they would have to write something down in order for me to respond (Which I would let them know by a large sign and by my own words). If it is something hateful, I could simply ignore it, and pray for them and tell them more about the love of Jesus and how He desires to change their life.
If I heard someone say, who are you to judge, I would say, Jesus came not to judge but to save. Let Him into your life and change your mind about what is good and right. Jesus does not need to be your judge. He can be your Savior. Your life line. Your long lost friend. Jesus loves you. He loves everyone and desires all to repent and to obey Him.
I would have pictures of hearts, silhouettes of the Lord's suffering, and him on the cross (not a white version of Jesus). I would provide verses like John 3:16 and other love verses and for them to seek forgiveness with Jesus today. I would encourage them to take material (with the Word of God in it) that could help them to accept Jesus and to walk uprightly in Him.
I would dress nice (white collared shirt, and maybe a writer's sports coat sometimes); But I would not wear a full matching suit and tie.
I would speak in love and yet warn them ever so subtly. I will tell them not to miss out on His love. Jesus will be coming soon. Love the Lord Jesus with everything you got. If your marriage is in shambles. Love Jesus. If your life is at the end of it's rope. Love Jesus. Focus on the Lord, and He will give you a new perspective and new eyes to see. He will help you to love like never before. Jesus is the way. Jesus loves us so very much.
These are the words I would say to them.
Please feel free to take any of my ideas or words here and run with them.
Anyways, I hope what I said here helps.
May you pray and feel guided to do what the Lord is calling you to do for His Kingdom, brother.
