Doct The sincerity of our love to our Brethren, is the security of our con∣sciences and estates before God.
Ʋse 1. To reprove the Popish doctrine, That it is impossible to have a certainty of salvation. The Apostle saith here, We assure our hearts before God.
2. Of exhortation unto brotherly love in sincerity, and to grow up in it. A man may give all that he hath, and yet not know love. Get your hearts purifi∣ed from all lusts. The Word of God will purifie you, Psal. 119.9. You shall finde a fresh spring of love bubling up and streaming forth, and though your Brethren cannot recompence it to you, yet you shall have peace.
3. See here a means to seal confidence and beliefe of hearts. Cleanse your hearts from sin, that hinders brotherly love.
4. Of comfort to those that love the Brethren heartily; you may be assu∣red of your good estates,
