I find it interesting that as you gave your personal testimony about how "you" came around, you also answered your own question without even realizing it. We're not adopted, we're grafted. Religion is one man's experience adopted by others who've not had an experience of their own. You've had a personal awakening that only "you" can comprehend, and even then it's hard to put that spiritual experience into natural words. But the truth is it's not something others can "adopt". They have to have a birthing of their own. But what "you" do is, you plant the seed in them just like it was planted in you. Your testimony explains exactly how that worked. The seed was planted, the spirit watered it through the reading of the Word, your mind wrestled with it, but as it grew, it caused you to "expand". And when the birthing came, it wasn't because you adopted someone else's version of something. You saw it because something "birthed" in you.
Trying to rely on just what Scripture says on a matter really isn't as effective as we've been led to believe simply because it's a book of signs intended to water what's already been planted. We're not to "build" up a belief from what our minds have already filtered through our reading of the Scripture. Faith doesn't come by reading . . .it doesn't even come by knowing. It comes by "hearing" and once we "hear" only then can we "see". Many still spend hours reading and building doctrines on what they see but because they can't "hear" what they see is tainted from the beginning.
People have mindsets just like you. You can give them Scriptures that say the opposite of what they think and it really won't matter because it's not based on what truth says, it's based on what they "think" it says. But . . .if you just love on them and be their friend, you become a planter instead of a warrior . . .God will use that to impregnate them with the truth and then they'll have a personal experience of their own that will change them . . .and THEN . . .their eyes will be opened to see. Even when John was in the spirit and heard the voice . . .he still had to turn around in order to SEE it.
