John Calvin, Commentary on Titus 3:4
Goodness and love. He has with propriety assigned the first rank to �goodness,� which prompts God to love us; for God will never find in us anything which he ought to love, but he loves us because he is good and merciful. Besides, although he testifies his goodness and love to all, yet we know it by faith only, when he declares himself to be our Father in Christ. Before Paul was called to the faith of Christ, he enjoyed innumerable gifts of God, which might have given him a taste of God�s fatherly kindness; he had been educated, from his infancy, in the doctrine of the law; yet he wanders in darkness, so as not to perceive the goodness of God, till the Spirit enlightened his mind, and till Christ came forth as the witness and pledge of the grace of God the Father, from which, but for him, we are all excluded Thus he means that the kindness of God is not revealed and known but by the light of faith.
