Love not expressed is like a seed planted in the dark ground and neglected. Without water or sunlight it fails to grow; it never blossoms; it does not produce fruit. The seed that was full of enormous potential never becomes what it was intended to be. Rather, the barren ground leads one to question whether it existed at all.

What good is it, my brothers, if someone says he has faith but does not have works? Can that faith save him? If a brother or sister is poorly clothed and lacking in daily food, and one of you says to them, “Go in peace, be warmed and filled,” without giving them the things needed for the body, what good is that? So also faith by itself, if it does not have works, is dead.
James 2:14-17, ESV
