1Jn 5, 20-21 We are in the one who is true his Son Jesus

(1Jn 5, 20-21) We are in the one who is true his Son Jesus
[20] We also know that the Son of God has come and has given us discernment to know the one who is true. And we are in the one who is true, in his Son Jesus Christ. He is the true God and eternal life. [21] Children, be on your guard against idols.

(CCC 217) God is also truthful when he reveals himself - the teaching that comes from God is "true instruction" (Mal 2:6). When he sends his Son into the world it will be "to bear witness to the truth" (Jn 18:37): "We know that the Son of God has come and has given us understanding, to know him who is true" (1 Jn 5:20; cf. Jn 17:3). (CCC 2087) Our moral life has its source in faith in God who reveals his love to us. St. Paul speaks of the "obedience of faith" (Rom 1:5; 16:26) as our first obligation. He shows that "ignorance of God" is the principle and explanation of all moral deviations (cf. Rom 1:18-32). Our duty toward God is to believe in him and to bear witness to him. (CCC 2097) To adore God is to acknowledge, in respect and absolute submission, the "nothingness of the creature" who would not exist but for God. To adore God is to praise and exalt him and to humble oneself, as Mary did in the Magnificat, confessing with gratitude that he has done great things and holy is his name (cf. Lk 1:46-49). The worship of the one God sets man free from turning in on himself, from the slavery of sin and the idolatry of the world.
