Galatians 6:14 "May I never boast except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world."
Have you ever seen that cooking show where the man unveils the secret ingredient? "...and tonights secret ingredient is...SUSHI!" Then the competitors must create a dish or meal around the secret ingredient? Imagine if one of the competitors went to work, creating a fantastic meal, but did not include any sushi. So when he stood before the judges at the end, what should he expect? Perhaps he might argue that he didn't really care for sushi. I doubt that would change their decision.
And when we stand in judgment, what will we say if we have ignored the cross. Do you really think God will accept something like, "But I really don't care for the cross. That whole Mel Gibson thing was so gross. But I got everything else right."
Without the cross, nothing else is right. Nothing.
