Thus, the theologian of glory will no doubt understand the word power , when applied to God, as referring to something analogous to a king’s power: imposing and coercive. Yet the theologian of the cross gives the word different content: power is there revealed in and through weakness. Then there is the idea of wisdom . The theologian of glory will understand wisdom in terms set by the world around, perhaps seeing it as intelligence or the knowledge of how to play the system. The theologian of the cross understands wisdom in terms of the incarnate God hanging weak and broken on a cross: a contradiction of all that the wise of the world around us would expect from the sovereign Creator. The theologian of glory will understand righteousness as an outward, visible quality constituted by good works. The theologian of the cross sees it in the one who is sinless yet made sin for others. The theologian of glory sees life and death as antitheses, and the latter as something to be avoided. The theologian of the cross understands that death is actually the gateway to true life.
