In Jesus Christ God not only speaks to man but also seeks him out. The Incarnation of the Son of God attests that God goes in search of man. Jesus speaks of this search as the finding of a lost sheep (cf. Lk 15:1-7). It is a search which begins in the heart of God and culminates in the Incarnation of the Word. If God goes in search of man, created in his own image and likeness, he does so because he loves him eternally in the Word, and wishes to raise him in Christ to the dignity of an adoptive son. God therefore goes in search of man who is his special possession in a way unlike any other creature. Man is God’s possession by virtue of a choice made in love: God seeks man out, moved by his fatherly heart.
Why does God seek man out? Because man has turned away from him, hiding himself as Adam did among the trees of the Garden of Eden (cf. Gen 3:8-10). Man allowed himself to be led astray by the enemy of God (cf. Gen 3:13). Satan deceived man, persuading him that he too was a god, that he, like God, was capable of knowing good and evil, ruling the world according to his own will without having to take into account the divine will (cf. Gen 3:5). Going in search of man through his Son, God wishes to persuade man to abandon the paths of evil which lead him farther and farther afield. “Making him abandon” those paths means making man understand that he is taking the wrong path; it means overcoming the evil which is everywhere found in human history. Overcoming evil: this is the meaning of the Redemption. This is brought about in the sacrifice of Christ, by which man redeems the debt of sin and is reconciled to God. The Son of God became man, taking a body and soul in the womb of the Virgin, precisely for this reason: to become the perfect redeeming sacrifice. The religion of the Incarnation is the religion of the world’s Redemption through the sacrifice of Christ, wherein lies victory over evil, over sin and over death itself. Accepting death on the Cross, Christ at the same time reveals and gives life, because he rises again and death no longer has power over him.
The religion which originates in the mystery of the Redemptive Incarnation, is the religion of “dwelling in the heart of God“, of sharing in God’s very life. Saint Paul speaks of this in the passage already quoted: “God has sent the Spirit of his Son into our hearts, crying, ‘Abba! Father!’ ” (Gal 4:6). Man cries out like Christ himself, who turned to God “with loud cries and tears” (Heb 5:7), especially in Gethsemane and on the Cross: man cries out to God just as Christ cried out to him, and thus he bears witness that he shares in Christ’s sonship through the power of the Holy Spirit. The Holy Spirit, whom the Father has sent in the name of the Son, enables man to share in the inmost life of God. He also enables man to be a son, in the likeness of Christ, and an heir of all that belongs to the Son (cf. Gal 4:7). In this consists the religion of “dwelling in the inmost life of God”, which begins with the Incarnation of the Son of God. The Holy Spirit, who searches the depths of God (cf. 1 Cor 2:10), leads us, all mankind, into these depths by virtue of the sacrifice of Christ. –from Tertio Millennio Adveniente (1994)
