After John had been arrested, Jesus came to Galilee proclaiming the gospel of God: "This is the time of fulfillment. The kingdom of God is at hand. Repent, and believe in the gospel."
Conversion. The Greek word for converting means: to rethink-to question one's own and common way of living; to allow God to enter into the criteria of one's life; to not merely judge according to the current opinions. Thereby, to convert means: not to live as all the others live, not do what all do, not feel justified in dubious, ambiguous, evil actions just because others do the same; begin to see one's life through the eyes of God; thereby looking for the good, even if uncomfortable; not aiming at the judgment of the majority, of men, but on the justice of God-in other words: to look for a new style of life, a new life.
All of this does not imply moralism; reducing Christianity to morality loses sight of the essence of Christ's message: the gift of a new friendship, the gift of communion with Jesus and thereby with God. Whoever converts to Christ does not mean to create his own moral autarchy for himself, does not intend to build his own goodness through his own strengths.
"Conversion" (metanoia) means exactly the opposite: to come out of self-sufficiency to discover and accept our indigence-the indigence of others and of the Other, his forgiveness, his friendship. Unconverted life is self-justification (I am not worse than the others); conversion is humility in entrusting oneself to the love of the Other, a love that becomes the measure and the criteria of my own life. - Pope Benedict XVI (Joseph Cardinal Ratzinger )
