I love my Uncle but we don't see eye to eye...

We're both schizophrenic, but I surrendered to Christ, and my Uncle surrendered to psychics 😫And that makes me really really really sad..... The other day we were talking about our experiences and he claimed to be the strongest of psychics, and that he goes to other psychics all the time and how powerful they are, it just broke my heart, I was like Uncle isn't that how we became schizophrenic in the first place????? He never repented and I did... I was like don't you care about eternity? Like you do know that psychics don't have innocent angels guiding them but impure spirits and demons disguising themselves as angels of light but in reality they're discieving spirits and the end result is eternal damnation in hell for all eternity right? I was like you could repent for the Kingdom of Heaven is near!!! Cause I really really care, I mean I love him I don't want to not be with me in Heaven with Jesus Christ!!! I was sad after talking to him because he was so set in his ways... I mean what can I say or do to help him see that the world is not flat you know what I mean?? There was a saint in our family who was sainted by the Pope back in the Fall of 2010 named Saint Andre Bessette he is a Cousin or Uncle in my lineiage and my Uncle blamed him for harming him!! I'm like Noooo We are blessed down to the thousandth generation because of HIM!! That's what the Bible says!! At least I was blessed because of him because I wanted to be like him, when I read a book about him... And God blessed me and others while God started healing people around me when I asked Him if He could.... What a blessing!!! Then my uncle said that he was a light worker and that he was a healer too, I'm like hmm I too am in the Light, but I am no healer, God is not me, I just ask Him to! That's the thing psychics think they have the powers, Christians believe God has the power, not us! All glory be Unto God!!! I don't know should I keep on trying to lead my uncle to Jesus Christ? I don't want him to not go to Heaven. I know it's a crazy topic to talk about not most would feel comfortable talking about it, but I feel it has to be offered in love and compassion and in truth.
