This is so scary. I have been trying to warn my unsaved brother about what is coming and just found out he recently earned a masters degree in sustainability! Of course he thinks my cautions about the SDG's are hogwash....along with everything else. He basically told me I am free to believe what I want. Same response from my unsaved sister and her family. She says we will still be here doing our thing in another 30 years.
Blue, it is so difficult to get family to hear us. Even Jesus had this problem. One of the things I do is pray that God will bring someone to them that they will have an ear for and have them present the gospel to them. I'm not suggesting that you give up but it I would pray for that too. I do it for my family. That way the words you have already spoken will help soften up their hearts.
