They are not dead.
John 3:16
Every believer has eternal life within them even as they live out their days on the earth. But I buried my brother. His soul and spirit are guaranteed eternal life for his faith in Jesus. But his physical death puts him beyond talking to. God can address him. Not me. And he would heartily agree. We wait for the resurrection. We can talk then. And we'll have a lot to talk about. Like perhaps the time someone tried to use John 3:16 to deny Hebrews 9:27 in order to justify disobeying God's explicit directions to avoid talking to those who have passed on. He will probably think I am kidding him, because it will, in that day, seem so ridiculous as to be impossible it ever happened.
