Evangelist explains that the world wants nothing to do with the Cross—that is, human beings naturally look for ways to justify their behavior instead of facing their sin. The “Son of the Bond-woman” refers to an allegorical passage in the Epistle to the Galatians. In short, it means that the Old Testament law (symbolized by Mount Sinai) cannot free a person from sin. Since Legality himself is in bondage, he can be of no benefit to burdened Christian, the Wiseman’s claim notwithstanding. Mt. Sinai’s curse refers to the curse that falls on all those who fail to keep the law flawlessly.
