If one has friends or acquaintances willing to discourse with you about what’s “real” and what’s “not,” would performing a Lightworker Healing Protocol session for them, potentially help them to be more open-minded and receptive to what you have to share?

This could well be the case. It will not address the issue of faith and belief directly but can remove barriers to free-thinking and internal corruption that would amplify a reaction to dig in their heels and resist any counterargument to their inner beliefs of the moment. There are many factors in play always as humans are quite complex and have many layers and many conflicting inner beliefs in actual fact, and this is why people will not always be rigid and immovable. They may have enough inner awareness and knowledge based on reason and logic that could come into play, given an opportunity, and persuade them within to change their views. Those are the ones who are reachable. It is difficult to know going in who you are dealing with, how categorical their thinking might be, and how intransigent they will prove to be in any attempt to win them over, but one must start somewhere. People can always use healing so there is nothing to lose in doing an outreach on their behalf. It is not truly a selfish act as it might seem on the surface, nor will it be coercion as this is never done by the divine realm. As you know, much to your disappointment at times, we are bending over backward always to allow humans their full array of choices whether it is good for them or not, but if they decree they want something to be a certain way we will not countermand their decisions. Their only consequence will then be theirs, having engineered it to their liking even if based on faulty information and poor decision making.
