For me, the best approach has been to simply walk up to anyone and everyone and say, “We’re just walking around town looking for people to pray for. What can we pray for you about? Do you have any pain or sickness? What about family or relational needs? Do you need a job or finances? We’ll pray for anything.” Most people won’t feel comfortable sharing right away and will say something like, “No, I’m good.” I expect them to say no at first, and my follow-up question is to simply ask, “Well, could I just pray a prayer of blessing for you right now?” Very few people say no to that even if they aren’t willing to name a specific request. I find that offering prayer is the most direct approach to evangelism, without too much beating around the bush or having people wonder what you’re getting at.
