We might say the whole mystery of our redemption in Christ, by his incarnation, his death and his resurrection, consists of this marvelous exchange: in the heart of Christ, God has loved us humanly, so as to render our human hearts capable of loving divinely. God became man so that man might become God—might love as only God is capable of loving, with the purity, intensity, power, tenderness, and inexhaustible patience that belong to divine love.50 It is an extraordinary source of hope and a great consolation to know that, by virtue of God’s grace working in us (if we remain open to it by persevering in faith, prayer, and the sacraments), the Holy Spirit will transform and expand our hearts to the point of one day making them capable of loving as God loves.
There is only one thing to live for: love. There is only one unhappiness: not to love God. That is what pains me on these days of recollection, to see my own soul so full of movement and shadows and vanities, cross-currents of dry wind, stirring up the dust and rubbish of desire.
