Grace is necessary to salvation, free will equally so - but grace in order to give salvation, free will in order to receive it.
Bernard of ClairvauxI do a great wrong in His sight, when I beseech Him that He will hear my prayer, which as I give utterance to it, I do not hear myself. I entreat Him that He will think of me; but I regard neither myself nor Him. Nay, what is worse, turning over corrupt and evil thoughts in mine heart, I thrust a dreadful offensiveness into His presence.
Bernard of ClairvauxWe are to love God for Himself, because of a twofold reason; nothing is more reasonable, nothing more profitable.
