If you love and serve others from the heart, you do not say evil words to them including jokes but only gentle and good words all the time. It is good for you to say good words without hurting others' heart, but much better for you to move the hearts of those who hurt you with good words. Jesus, the Son of God, became flesh and came down to this world. He showed the best goodness by laying down His life for all men who were sinners. Moreover, He acknowledges those who are endeavoring to accomplish such goodness as His friends.
"Greater love has no one than this, that one lay down his life for his friends. You are My friends, if you do what I command you." (John 15:14-14)
