I would like to offer my condolences to your family. Job 14:14 asks: "If a man dies, can he live again?" The answer is yes. Not only do you have the prospect of seeing Mr. Thweatt again through the resurrection, but he will never again experience "death", "mourning", "outcry" or "pain" - Revelation 21:4. I hope faith in God and the Bible provide comfort to you and your family.
