2. The Gospel of the kingdom links Christ with the Sacred Scriptures that, using a royal image, celebrate God's lordship over the cosmos and history. Thus we read in the Psalter: "Say among the nations, "The Lord reigns! Yea, the world is established, it shall never be moved; he will judge the peoples'" (Ps 96: 10). The kingdom is thus God's effective but mysterious action in the universe and in the tangle of human events. He overcomes the resistance of evil with patience, not with arrogance and outcry.
For this reason Jesus compares the kingdom of God to a mustard seed, the smallest of all seeds, but destined to become a leafy tree (cf. Mt 13: 31-32), or to the seed a man scatters on the ground: "he sleeps and rises night and day, and the seed sprouts and grows, he knows not how" (Mk 4: 27). The kingdom is grace, God's love for the world, the source of our serenity and trust: "Fear not, little flock", Jesus says, "for it is your Father's good pleasure to give you the kingdom" (Lk 12: 32). Fears, worries and nightmares fade away, because in the person of Christ the kingdom of God is in our midst (cf. Lk 17: 21).
3. But man is not a passive witness to God's entrance into history. Jesus asks us "to seek" actively "the kingdom of God and his righteousness" and to make this search our primary concern (Mt 6& ;33). To those who "supposed that the kingdom of God was to appear immediately" (Lk 19: 11), he prescribed an active attitude instead of passive waiting, telling them the parable of the 10 pounds to be used productively (cf. Lk 19: 12-27). For his part, the Apostle Paul states that "the kingdom of God does not mean food and drink but righteousness" (Rom 14: 17) above all, and urges the faithul to put their members at the service of righteousness for sanctification (cf. Rom 6: 13, 19).
The human person is thus called to work with his hands, mind and heart for the coming of God's kingdom into the world. This is especially true of those who are called to the apostolate and are, as St Paul says, "fellow workers for the kingdom of God" (Col 4: 11), but it is also true of every human person.

Winning with good
1. At the beginning of the New Year, I once again address the leaders of nations and all men and women of good will, who recognize the need to build peace in the world. For the theme of this 2005 World Day of Peace I have chosen Saint Paul's words in the Letter to the Romans: "Do not be overcome by evil, but overcome evil with good" (12:21). Evil is never defeated by evil; once that road is taken, rather than defeating evil, one will instead be defeated by evil.
The great Apostle brings out a fundamental truth: peace is the outcome of a long and demanding battle which is only won when evil is defeated by good. If we consider the tragic scenario of violent fratricidal conflicts in different parts of the world, and the untold sufferings and injustices to which they have given rise, the only truly constructive choice is, as Saint Paul proposes, to flee what is evil and hold fast to what is good (cf. Rom 12:9).
Peace is a good to be promoted with good: it is a good for individuals, for families, for nations and for all humanity; yet it is one which needs to be maintained and fostered by decisions and actions inspired by good. We can appreciate the profound truth of another saying of Saint Paul: "Repay no one evil for evil" (Rom 12:17). The one way out of the vicious circle of requiting evil for evil is to accept the Apostle's words: "Do not be overcome by evil, but overcome evil with good" (Rom 12:21).
