God's message to humanity is eternal and invariable. As our Maker, he has always emphasized the importance of having a relationship with him. To Abraham he said: "And I will establish my covenant between me and you, and your descendants after you in their generations, for an everlasting covenant, to be your God, and your descendants after you" (Genesis 17: 7). Years later he said almost the same to the people of Israel (Deuteronomy 29:13).
The expression Kingdom of God implies much more than the administration of Jesus Christ of the just laws of God throughout the world. It also applies to the children of God himself, who has revealed that the members of that family, which he is currently creating, are his sons and daughters and that, together with Jesus Christ, they will administer their laws over the nations.
