Redemptoris Missio §14

¹⁴ Jesus gradually reveals the characteristics and demands of the kingdom through his words, his actions and his own person. The kingdom of God is meant for all mankind, and all people are called to become members of it. To emphasize this fact, Jesus drew especially near to those on the margins of society, and showed them special favor in announcing the Good News. At the beginning of his ministry he proclaimed that he was "anointed...to preach good news to the poor" (Lk 4:18). To all who are victims of rejection and contempt Jesus declares: "Blessed are you poor" (Lk 6:20). What is more, he enables such individuals to experience liberation even now, by being close to them, going to eat in their homes (cf. Lk 5:30; 15:2), treating them as equals and friends (cf. Lk 7:34), and making them feel loved by God, thus revealing his tender care for the needy and for sinners (cf. Lk 15:1-32). The liberation and salvation brought by the kingdom of God come to the human person both in his physical and spiritual dimensions. Two gestures are characteristic of Jesus' mission: healing and forgiving. Jesus' many healings clearly show his great compassion in the face of human distress, but they also signify that in the kingdom there will no longer be sickness or suffering, and that his mission, from the very beginning, is meant to free people from these evils. In Jesus' eyes, healings are also a sign of spiritual salvation, namely liberation from sin. By performing acts of healing, he invites people to faith, conversion and the desire for forgiveness (cf. Lk 5:24). Once there is faith, healing is an encouragement to go further: it leads to salvation (cf. Lk 18:42-43). The acts of liberation from demonic possession-the supreme evil and symbol of sin and rebellion against God-are signs that indeed "the kingdom of God has come upon you" (Mt 12:28).
