2:15 {19} For so is the will of God, that with well doing ye may put to silence the ignorance of foolish men:
(19) He declares the first argument more amply, showing that Christian liberty does among all things least or not at all consist in this, that is, to cast off the bridle of laws (as at that time some altogether unskilful in the kingdom of God reported) but rather in this, that living holy lives according to the will of God, we should reveal to all men, that the gospel is not a cloak for sin and wickedness, seeing we are free of this sort, that yet we are still the servants of God, and not of sin.
2:15 That with well doing ye may put to silence the ignorance of foolish men. It is God's will that thus you may silence the charge that you are seditious persons.
2:15 The ignorance - Of them who blame you, because they do not know you: a strong motive to pity them.
2:13-17 A Christian conversation must be honest; which it cannot be, if there is not a just and careful discharge of all relative duties: the apostle here treats of these distinctly. Regard to those duties is the will of God, consequently, the Christian's duty, and the way to silence the base slanders of ignorant and foolish men. Christians must endeavour, in all relations, to behave aright, that they do not make their liberty a cloak or covering for any wickedness, or for the neglect of duty; but they must remember that they are servants of God.
