<p>3:6 <i>That the Gentiles are fellow-heirs and fellow-members of the body and fellow-partakers of the promise in Christ Jesus through the gospel</i>- This is &quot;the mystery of Christ&quot; of :4. &quot;The Gospel&quot; had already been revealed to Abraham, in the form of the promises which clearly implied the acceptance of the Gentiles into His seed (Gal. 3:8). But as noted on :5, this (now) obvious truth had to be revealed by the Spirit. The words on paper required an interpretation which was given by the Spirit at the right time. The delay in revealing this truth was surely because the body of Christ was not then in existence, and His work and sacrifice had not then been completed. And seeing He had genuine freewill, there was the possibility He could have failed. In this we see the thrill of victory when he finally dies perfect and morally triumphant, and the endless wonder and significance of His resurrection. &nbsp;</p>
