A tenderhearted person lives a blessed life;my 2cents...
a hardhearted person lives a hard life. (proverbs 28:14- the message)
We live in an age of protection- from pollution, from crime, from terrorism, from STDs... from pain. We learn to build walls to protect, even around our hearts. A wall around the heart keeps everything out, the good and the bad leading to a lonely, shriveled up heart/life.
Stacey and I saw a funny movie on this very topic this past weekend called Ghosttown about a man (played by Ricky Gervais) who had been hurt so much in the past that he did not want to risk the pain again. The man lives a lonely, uncaring and unfeeling existence until something happens that opens a crack in the door of his heart. The result (spoiler alert) is that he not only allows love into his heart, but he then opens his life to love others.
And that sums up this Proverb- when we are loved and love others, we're blessed.
