On the one hand, God is holy and just and cannot tolerate or live with or bless evil. On the other hand, God is loving and faithful and cannot tolerate the loss of people he has committed himself to. This is a tremendous, seemingly irresolvable tension in the narrative—and also in the whole Bible (see, for instance, Exodus 34:6-7; Hosea 11:1-11). This tension is what should keep us in suspense throughout Judges. Will God finally give up on his people (but then what of his faithfulness)? Or will he finally give in to his people (but then what of his holiness)?
It is only on the cross that we can understand how God is able to resolve the tension. On the cross, our sin was given—imputed—to him, so that his righteousness could be imputed to us. On the cross, “God made him who had no sin to be sin for us, so that in him we might become the righteousness of God” (2 Corinthians 5:21). On the cross, God poured out his wrath on his people in the person of his Son. He satisfied both justice, because sin was punished, and loving faithfulness, since he is now able to accept and forgive us. Only through the cross can God be both “just and the justifier of the one who has faith in Jesus” (Romans 3:26, ESV). This is the only way the tension of Judges can be resolved; the only way that God can love us both conditionally and unconditionally.
