The joy the Gospel brings is only intensified in the love you show to others. John Piper has stressed this in his writings. He put it like this. “Love is the overflow of joy in God! It is not duty for duty's sake, or right for right's sake. It is not a resolute abandoning of one's own good with a view solely to the good of the other person. It is first a deeply satisfying experience of the fullness of God's grace, and then a doubly satisfying experience of sharing that grace with another person.”
