Therefore, having been justified by faith, we have[a] peace with God through our Lord Jesus Christ, 2 through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God.
def an act of favor given freely, without claim or expectation of return
The word charis in the New Testament's exalted context refers to God's offer of salvation which was procured by Jesus on the cross. Christ's substitutionary death for payment of sin on the cross, offered to sinners who only deserve punishment, was given freely with no claim or expectation of return but given out of His bountiful love. Only God in His infinite grace makes salvation possible.
