who did not sin, "neither was deceit found in his mouth."
      (4.) He reminds them of the spiritual nature of Christian liberty. The Jews, from Deuteronomy 17:15, concluded that they were bound to obey no sovereign but one taken from their own brethren; and the converted Jews thought they were free from subjection by their relation to Christ. To prevent their mistakes, the apostle tells the Christians that they were free, but from what? Not from duty or obedience to God's law, which requires subjection to the civil magistrate. They were free spiritually from the bondage of sin and Satan, and the ceremonial law; but they must not make their Christian liberty a cloak or covering for any wickedness, or for the neglect of any duty towards God or towards their superiors, but must still remember they were the servants of God. Learn, [1.] All the servants of Christ are free men (John 8:36); they are free from Satans' dominion, the law's condemnation, the wrath of God, the uneasiness of duty, and the terrors of death. [2.] The servants of Jesus Christ ought to be very careful not to abuse their Christian liberty; they must not make it a cover or cloak for any wickedness against God or disobedience to superiors.
