Love
Love without sacrifice is mere sentimentality. (Timothy Keller, late author and pastor)
A lot of songs and poems are about love, but a quick look reveals that most of them are mere expressions of sentiment—feelings. Genuine love, however most often costs something, even sacrifice. The New Testament writer, Paul describes such sacrifice as “meaningless if made without love for others,” the kind of love that may indeed cost a great deal.
If I gave everything I have to the poor and even sacrificed my body, I could boast about it; but if I didn’t love others, I would have gained nothing (1 Corinthians 13:3).
