That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
Intent of 'Christ becoming a curse for us'-`that unto ( eis (G1519)) the Gentiles the blessing of Abraham
(i:e., promised to Abraham-namely, justification by faith) might come in х en (G1722)] Christ Jesus' (not in the law) (cf. Galatians 3:8).
That we (Jews and Gentiles alike) might receive the promise of the Spirit - the promised Spirit (Joel 2:28-29; Luke 24:49). This clause follows not that immediately preceding (for our receiving the Spirit is not the result of the blessing of Abraham coming on the Gentiles), but "Christ hath redeemed us," etc.
Through faith - not by works. Here he resumes Galatians 3:2.
