A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another. By this all people will know that you are my disciples, if you have love for one another.” —John 13:34-35 ESV
J.C. Ryle encourages us to actually love, to obey this command of Jesus:
Let us take heed that this well-known Christian grace is not merely a notion in our heads, but a practice in our lives. Of all the commands of our Master there is none which is so much talked about and so little obeyed as this. Yet, if we mean anything when we profess to have charity and love toward all men, it ought to be seen in our tempers and our words, our bearing and our doing, our behavior at home and abroad, our conduct in every relation of life. Specially it ought to show itself forth in all our dealing with other Christians. We should regard them as brethren and sisters, and delight to do anything to promote their happiness. We should abhor the idea of envy, malice, and jealousy towards a member of Christ, and regard it as a downright sin. This is what our Lord meant when He told us to love one another.
