Hatred can be communicated in one sentence. Love has to be lived out. (John Shirk, contemporary American poet)
A hateful thought or word can be expressed in an instant of time, but the effects will be long-lasting. Love, on the other hand, can be thought and expressed in a moment, but it takes a long and persistent commitment to be realized and effective.
Hatred stirs up dissension, but love covers over all wrongs. (Proverbs 10:12)
