It does not mean, in good Greek fashion, God’s graciousness, nor concetely his free love (Taylor).

“Against a still common view it must be stated that in Paul χαρις does not mean primarily a divine attribute (Wobbe, Charis-Gedanke, 32). We have gradually come to speak of grace as an inherent quality in man, just as we talk of gifts whereas it is in reality the communication of Divine goodness by the inworking of the Spirit, and through the medium of Him who is ‘full of grace and truth.’” - Robert Girdlestone, Synonyms of the Old Testament (London: Longmans, Green and Co., 1871), p. … In the great proportion of passages in which the word grace is found in the New Testament, it signifies the unmerited operation of God in the heart of man, effected through the agency of the Holy Spirit.
