“Why the law was our schoolmaster to bring us to Christ, that we might be justified by faith.” Galatians 3:24.
When the mind is drawn to the cross of Calvary, Christ by imperfect sight is discerned on the shameful cross. Why did He die? In consequence of sin. What is sin? The transgression of the law. Then the eyes are open to see the character of sin. The law is broken but cannot pardon the transgressor. It is our schoolmaster, condemning to punishment. Where is the remedy? The law drives us to Christ, who was hanged upon the cross that He might be able to impart His righteousness to fallen, sinful man and thus present men to His Father in His righteous character.
There is no safety nor repose nor justification in transgression of the law. Man cannot hope to stand innocent before God, and at peace with Him through the merits of Christ, while he continues in sin. He must cease to transgress, and become loyal and true. As the sinner looks into the great moral looking glass, he sees his defects of character. He sees himself just as he is, spotted, defiled, and condemned. But he knows that the law cannot in any way remove the guilt or pardon the transgressor. He must go farther than this. The law is but the schoolmaster to bring him to Christ. He must look to his sin-bearing Saviour. And as Christ is revealed to him upon the cross of Calvary, dying beneath the weight of the sins of the whole world, the Holy Spirit shows him the attitude of God to all who repent of their transgressions. “For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life” (John 3:16). –Selected Messages, book 1, pp. 341, 213.
