The Center of the Old Testament

Bruce Waltke:

[T]he center of the OT, the message that accommodates all its themes, is that Israel’s sublime God, whose attributes hold in tension his holiness and mercy, glorifies himself by establishing his universal rule over his volitional creatures on earth through Jesus Christ and his covenant people.
