Grace is more than mercy and love. It super-adds to them. It denotes, not simply love, but the love of a sovereign, transcendent Superior. One that may do what He will. That may wholly choose whether He will love or no. Now God, who is an infinite Sovereign, who might have chosen whether ever He would love us or no; for Him to love us, this is Grace.
Thomas GoodwinGod works with power, and can make the unwilling willing; if He undertakes the conversion of a soul, it will be converted. All the pious workings of our heart towards God are the fruit and consequence of the powerful working of His grace in us.
