Calvin 

“Here a rich truth presents itself to us, to which I shall briefly refer, and leave it to be meditated upon by each individual: Paul does by no means ascribe the praise of our salvation to ourselves, but derives it altogether from the fountain of God’s free and paternal love towards us; for he makes this the first thing — God loves us: and what is the cause of his love, except his own goodness alone? On this depends our calling, by which in his own time he seals his adoption to those whom he had before freely chosen. ”
