“But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another . . . but we beseech you, brethren, that ye increase more and more’ (I Thess, 4.9, 10).
God himself has undertaken to teach brotherly love; all that men can add to it is to remember this divine instruction and the admonition to excel in it more and more. When God was merciful, when he revealed Jesus Christ to us as our Brother, when he won our hearts by his love, this was the beginning of our instruction in divine love. When God was merciful to us, we learned to be merciful with our brethren. When we received forgiveness instead of judgment, we, too, were made ready to forgive our brethren. What God did to us, we then owed to others. The more we received, the more we were able to give; and the more meagre our brotherly love, the less were we living by God’s mercy and love. Thus God himself taught us to meet one another as God has met us in Christ. ‘Wherefore receive ye one another,”
