Origin of Union with Christ

“The fountain of salvation itself in the eternal election of the Father is “in Christ.” Paul says: “Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in the heavenlies in Christ, even as he chose us in him before the foundation of the world” (Eph. 1:3, 4). The Father elected from eternity, but he elected in Christ. We are not able to understand all that is involved, but the fact is plain enough that there was no election of the Father in eternity apart from Christ. And that means that those who will be saved were not even contemplated by the Father in the ultimate counsel of his predestinating love apart from union with Christ–they were chosen in Christ. As far back as we can go in tracing salvation to its fountain we find “union with Christ”; it is not something tacked on; it is there from the outset” (John Murray, Redemption: Accomplished and Applied, 162).
