Waltke: The Center of the OT

In his OT theology (Zondervan 2007), Bruce Waltke helpfully suggests that "the center of the Old Testament, the message that accommodates all its themes, is that Israel's sublime God, whose attributes hold in tension his holiness and mercy, glories himself by establishing his universal rule over his volitional creatures on earth through Jesus Christ and his covenant people" (p. 144).
