In the New Testament the Greek word that corresponds to the English word grace is charis, a free unmerited supernatural gift of God given to us by God. There is no term in the Old Testament to match the New Testament technical sense of grace(1).

Rev 22:21 "May the Grace of the Lord Jesus be with you all." (JB)

2Cor 12:9 "My grace is sufficient for you, for my power is made perfect in weakness." (RSV)

Jn 1:16-17 "From his fullness we have all received, grace upon grace. The law indeed was given through Moses; grace and truth came through Jesus Christ." (NRSV)

Gal 2:21 "I do not nullify the grace of God; for if justification comes through the law, then Christ died for nothing." (NRSV)

1Cor 15:10 "By the grace of God I am what I am, and his grace toward me has not been in vain. On the contrary, I worked harder than any of them - though it was not I, but the grace of God that is with me." (NRSV)

Eph 2:8-9 "For by grace you have been saved through faith; and this is not your own doing, it is the gift of God - not the result of work, so that no one may boast." (NRSV)

2Pet 1:2 "May grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord." (RSV)

Jas 4:6 "God opposes the proud, but gives grace to the humble." (NRSV)
