"If I give away all I have, and if I deliver my body to be burned, but do not have love, I gain nothing" (v. 3). This hymn must be the Magna Carta of all ecclesial service; it sums up all the reflections on love which I have offered throughout this Encyclical Letter. Practical activity will always be insufficient, unless it visibly expresses a love for man, a love nourished by an encounter with Christ. My deep personal sharing in the needs and sufferings of others becomes a sharing of my very self with them: if my gift is not to prove a source of humiliation, I must give to others not only something that is my own, but my very self; I must be personally present in my gift.
This proper way of serving others also leads to humility. The one who serves does not consider himself superior to the one served, however miserable his situation at the moment may be. Christ took the lowest place in the world - the Cross - and by this radical humility he redeemed us and constantly comes to our aid. Those who are in a position to help others will realize that in doing so they themselves receive help; being able to help others is no merit or achievement of their own. This duty is a grace. The more we do for others, the more we understand and can appropriate the words of Christ: "We are useless servants" (Lk 17:10). We recognize that we are not acting on the basis of any superiority or greater personal efficiency but because the Lord has graciously enabled us to do so.
...we are only instruments in the Lord's hands; and this knowledge frees us from the presumption of thinking that we alone are personally responsible for building a better world. In all humility we will do what we can, and in all humility we will entrust the rest to the Lord.
When we consider the immensity of others' needs, we can, on the one hand, be driven toward an ideology that would aim at doing what God's governance of the world apparently cannot: fully resolving every problem. Or we can be tempted to give in to inertia, since it would seem that in any event nothing can be accomplished. At such times, a living relationship with Christ is decisive if we are to keep on the right path, without falling into an arrogant contempt for man, something not only unconstructive but actually destructive, or surrendering to a resignation which would prevent us from being guided by love in the service of others. (pgs. 50-51)
Even in their bewilderment and failure to understand the world around them, Christians continue to believe in the "goodness and loving kindness of God" (Tit 3:4). Immersed like everyone else in the dramatic complexity of historical events, they remain unshakably certain that God is our Father and loves us, even when his silence remains incomprehensible. (pg. 53)
Faith, hope, and charity go together. Hope is practiced through the virtue of patience, which continues to do good even in the face of apparent failure, and through the virtue of humility, which accepts God's mystery and trusts him even at times of darkness. Faith tells us that God has given his Son for our sakes and gives us the victorious certainty that it is really true: God is love! (pg. 54)
