21I do not set aside the grace of God, for if righteousness could be gained through the law, Christ died for nothing!”2:21 Some interpreters end the quotation after verse 14.
21I do not ignore or nullify the [gracious gift of the] grace of God [His amazing, unmerited favor], for if righteousness comes through [observing] the Law, then Christ died needlessly. [His suffering and death would have had no purpose whatsoever.]”
