Birth is a change from immortal to mortal. At death we lay our mortality down and enter the world of spirits preparatory to the resurrection where immortality is again ours, thus the saying from eternity to eternity.
The change that brings on eternal life must come by INVITATION and not MANDATE.
As missionaries we invite others to investigate by offering them features of the gospel. As members we invite our friends to share the gospel’s blessing by how we live and as parents we invite our children’s obedience by how we teach.
