Now who is he who will harm you, if you become imitators of that which is good?
      I. He teaches us how Christians and friends should treat one another. He advises Christians to be all of one mind, to be unanimous in the belief of the same faith, and the practice of the same duties of religion; and, whereas the Christians at that time were many of them in a suffering condition, he charges them to have compassion one of another, to love as brethren, to pity those who were in distress, and to be courteous to all. Hence learn, 1. Christians should endeavour to be all of one mind in the great points of faith, in real affection, and in Christian practice; they should be like-minded one to another, according to Christ Jesus (Romans 15:5), not according to man's pleasure, but God's word. 2. Though Christians cannot be exactly of the same mind, yet they should have compassion one for another, and love as brethren; they ought not to persecute or hate one another, but love one another with more than common affection; they should love as brethren. 3. Christianity requires pity to the distressed, and civility to all. He must be a flagrant sinner, or a vile apostate, who is not a proper object of civil courtesy, 1 Corinthians 5:11; 2 John 1:10; 2 John 1:11.
