“A single sunbeam is enough to drive away many shadows.” — St. Francis of Assisi
I see this in many meanings.
One, the single sunbeam is the Trinity and their love for us, while the shadows are the results of human choices and free will, original sin and all other sins.
Two, sometimes a single ray of hope is enough to dispel the shadows of depression and suicidal thoughts. This is a struggle in this life for me, though things have been looking up lately.
Three, quite literally, a single candle can light up a room or serve as a beacon for weary travelers. The first lights of dawn are enough to drive away the shadows in the night.
There are probably others, but I'm not thinking of them now. What do you see in that quote?
