When engineers would bridge a stream, they often carry over a single thread. Then strand is added to strand, until a foundation is laid for planks; and now the bold engineer finds safe footway, and walks from side to side. So God takes from us some golden threaded pleasure, and stretches it hence to heaven; then He takes a child and then a friend. Thus He bridges death, and teaches the thought of the most timid to find their way hither between the two spheres.
In this story, the Author is teaching us that God has a plan for all of us; but, just as the thread stretched across the river may seem strange at first, God, through his wisdom, shares with us his plan through his creation that He made and makes us to live and die to be with him forever in a new heaven and earth. – Hentycrew
