Spirituality: Love Rejoices, The Joy of Love, par. 110

110. When a loving person can do good for others, or sees that others are happy, they themselves live happily and in this way give glory to God, for “God loves a cheerful giver” (2 Cor 9:7). Our Lord especially appreciates those who find joy in the happiness of others. If we fail to learn how to rejoice in the well-being of others, and focus primarily on our own needs, we condemn ourselves to a joyless existence, for, as Jesus said, “it is more blessed to give than to receive” (Acts 20:35). The family must always be a place where, when something good happens to one of its members, they know that others will be there to celebrate it with them.
