Genesis 3:19: Dust, Death, and Cremation
Genesis 3:19 sets the return to dust as God's verdict on human sin, spoken before any funeral practice appears in Scripture. The verse says nothing about how a body is laid down, so burial and cremation are matters of wisdom rather than command.
Genesis 3:19: Dust, Death, and Christian Burial
Genesis 3:19 makes death God's declared verdict on sin: the man taken from the ground returns to the ground. Christian burial is an acted honesty about that verdict, done in the hope of resurrection rather than as a technique for securing anything beyond God's promise.
