He is not the God of the dead, but the God of the living.
Jesus is the only Teacher whose words concerning the other world we may safely believe. Other men only speculate; Jesus knows the things He declares. There is impenetrable mystery about the grave. Where are the dead? Is there anything after death? The words of Jesus to the Sadducees seem very plain, and they tell us much that we are eager to know. When He says of the dead that they are “as angels in heaven,” He probably has reference only to one matter, that they make up one community, and are not gathered again in separate families, as on earth.
The teaching of Jesus concerning the nature of death itself is far from important. “God is not the God of the dead, but of the living.” That is, Abraham, Isaac, and Jacob were not dead, but living that day at the burning bush. Moses and Elijah were living, too, in Christ’s own time, for they visited Him on the Transfiguration Mount. So our loved ones who believed in Christ are living just as really as ever they lived.
