QUOTE In the letter to the Galatians, [Saint Paul] provided for us a very personal profession of faith, in which he opens his heart to the reader of all times, and reveals the deep driving force of his life. ‘I live by faith in the Son of God who has loved me and given himself up for me’ (Gal. 2:20).
Everything that Paul does begins from this center. His faith is the experience of being loved by Jesus Christ in a completely personal way; it is the awareness of the fact that Christ has faced death not for some anonymous person, but out of love for him - for Paul - and that, as the Risen One, he still loves him. Christ gave himself up for him. His faith comes from being transfixed by the love of Jesus Christ, a love that shakes him to his core and transforms him. His faith is not a theory, an opinion about God and the world. His faith is the impact of the love of God on his heart. And thus his faith is itself love for Jesus Christ.
This love is now the law of his life, and in this very way it is the freedom of his life. He speaks and acts on the basis of the responsibility of love. Freedom and responsibility are here united in an inseparable way. Because he stands in the responsibility of love, he is free; because he is someone who loves, he lives completely in the responsibility of this love and does not take freedom as a pretext for willfulness and selfishness.
