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.

If I speak with the languages of men and of angels, but don’t have love, I have become sounding brass, or a clanging cymbal. If I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but don’t have love, I am nothing. If I give away all my goods to feed the poor, and if I give my body to be burned, but don’t have love, it profits me nothing.
1 Corinthians 13:1-3, WEB
