22. Hast thou faith--on such matters?
      have it to thyself--within thine own breast
      before God--a most important clause. It is not mere sincerity, or a private opinion, of which the apostle speaks; it is conviction as to what is the truth and will of God. If thou hast formed this conviction in the sight of God, keep thyself in this frame before Him. Of course, this is not to be over-pressed, as if it were wrong to discuss such points at all with our weaker brethren. All that is here condemned is such a zeal for small points as endangers Christian love.
      Happy is he that condemneth not himself in that which he alloweth--allows himself to do nothing, about the lawfulness of which he has scruples; does only what he neither knows nor fears to be sinful.
