1Jn 4, 9 The love of God was revealed to us

(1Jn 4, 9) The love of God was revealed to us
[9] In this way the love of God was revealed to us: God sent his only Son into the world so that we might have life through him.

(CCC 458) The Word became flesh so that thus we might know God's love: "In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him" (1 Jn 4:9). "For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life." (Jn 3:16). (CCC 516) Christ's whole earthly life - his words and deeds, his silences and sufferings, indeed his manner of being and speaking - is Revelation of the Father. Jesus can say: "Whoever has seen me has seen the Father", and the Father can say: "This is my Son, my Chosen; listen to him!" (Jn 14:9; Lk 9:35; cf. Mt 17:5; Mk 9:7, "my beloved Son"). Because our Lord became man in order to do his Father's will, even the least characteristics of his mysteries manifest "God's love… among us" (Jn 4:9). (CCC 517) Christ's whole life is a mystery of redemption. Redemption comes to us above all through the blood of his cross (Cf. Eph 1:7; Col 1:13-14; 2 Pt 1:18-19), but this mystery is at work throughout Christ's entire life: - already in his Incarnation through which by becoming poor he enriches us with his poverty (Cf. 2 Cor 8:9); - in his hidden life which by his submission atones for our disobedience (Cf. Lk 2:51); - in his word which purifies its hearers (Cf. Jn 15:3); - in his healings and exorcisms by which "he took our infirmities and bore our diseases" (Mt 8:17; cf. Isa 53:4); - and in his Resurrection by which he justifies us (Cf. Rom 4:25).
