I know how you feel and I know how that all goes. We keep praying because we know that Jesus hears us. I will be praying for them
Here is a thought. Maybe you could send them information as a secret admirer in a letter with a gift of some sort. That way you can share Jesus and proof of Him without them making you feel bad or telling you they don't want to hear it. Wow I have a secret admirer, Lol. Hard to argue with a secret admirer, Lol.
Maybe at the end you could say something like I've been looking for someone like you my whole life but I'm bashful to aproach you. Maybe you could help me. If you to believe what I was led to share with you about the Bible and Jesus would you put a red string and tie it on your visor in your car like a bow and maybe attend a certain church
Wise as a serpent, harmless as a dove
