Ephesians 1:9,10

"He has made known to us the mystery .." God's intentions were outlined to Abraham in Gen 12:1-3 when He promised that through him all nations on earth would be blessed. Yet in the subsequent period it seemed impossible that this would ever happen. For most of the Old Testament there is enmity between Israel and her neighbours, with other nations being enemies of both God and Israel. Moreover, the Old Testament could be described as a record of Israel's sins against God. How on earth was God's plan ever going to be fulfilled? Now the answer has been revealed, it is in and through Christ. God's good will and pleasure are completely fulfilled in Christ. The cross and resurrection are the pivotal points in all this, but the plans are still in the process of being fulfilled. Ie the gospel is continuing to spread throughout the earth, reaching people from every tribe and tongue. The plans will be fulfilled when everything is brought together in unity under Christ.

Christ is the centre of it all. There is no one else, and no other creed, through which God's plans will be fulfilled.
