VERSE 14. That the blessing of Abraham might come, on the Gentiles through Jesus Christ.
Paul always keeps this text before him: "In thy seed shall all the nations of the earth be blessed." The blessing promised unto Abraham could come upon the Gentiles only by Christ, the seed of Abraham. To become a blessing unto all nations Christ had to be made a curse to take away the curse from the nations of the earth. The merit that we plead, and the work that we proffer is Christ who was made a curse for us.
Let us become expert in the art of transferring our sins, our death, and every evil from ourselves to Christ; and Christ's righteousness and blessing from Christ to ourselves.
VERSE 14. That we might receive the promise of the Spirit through faith.
"The promise of the Spirit" is Hebrew for "the promised Spirit." The Spirit spells freedom from the Law, sin, death, the curse, hell, and the judgment of God. No merits are mentioned in connection with this promise of the Spirit and all the blessings that go with Him. This Spirit of many blessings is received by faith alone. Faith alone builds on the promises of God, as Paul says in this verse.
Long ago the prophets visualized the happy changes Christ would effect in all things. Despite the fact that the Jews had the Law of God they never ceased to look longingly for Christ. After Moses no prophet or king added a single law to the Book. Any changes or additions were deferred to the time of Christ's coming. Moses told the people: "The Lord thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken." (Deuteronomy 18:15.)
God's people of old felt that the Law of Moses could not be improved upon until the Messiah would bring better things than the Law, i.e., grace and remission of sins.
