The cross stands as a mystery because it is foreign to everything we exalt- self over principle, power over meekness, the quick fix over the long haul, cover-up over confession, escapism over confrontation, conform over sacrifice, feeling over commitment, legality over justice, the body over the spirit, anger over forgiveness, man over God.
The God of the Old Testament is arguably the most unpleasant character in all fiction: jealous and proud of it; a petty, unjust, unforgiving control-freak; a vindictive, bloodthirsty ethnic cleanser; a misogynistic, homophobic, racist, infanticidal, genocidal, filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully.
Outside of Christ, I am only a sinner, but in Christ, I am saved. Outside of Christ, I am empty; in Christ, I am full. Outside of Christ, I am weak; in Christ, I am strong. Outside of Christ, I cannot; in Christ, I am more than able. Outside of Christ, I have been defeated; in Christ, I am already victorious. How meaningful are the words, "in Christ."
