Remember how the Lord your God led you all the way in the wilderness these forty years, to humble and test you in order to know what was in your heart, whether or not you would keep his commands.
These have come so that the proven genuineness of your faith— of greater worth than gold, which perishes even though refined by fire— may result in praise, glory and honor when Jesus Christ is revealed.
In addition, we are sending with them our brother who has often proved to us in many ways that he is zealous, and now even more so because of his great confidence in you.
