Francis Schaeffer

At the close of his ministry, Jesus looks forward to his death on the cross, the open tomb and the ascension. Knowing that he is about to leave, Jesus prepares his disciples for what is to come. It is here that he makes clear what will be the
distinguishing mark of the Christian:

"My children, I will be with you only a little longer. You will look for me, and just as I told the Jews, so I tell you now: Where I am going, you cannot come. A new command I give you: Love one another. As I have loved you, so you must love one another. By this all men will know that you are my disciples, if you love one another." (John 13:33-35)

The first commandment is to love the Lord our God with all our heart, soul and mind. The second commandment bears the universal command to love men. Notice that the second commandment is not just to love Christians. It is far wider than this. We are to love our neighbor as ourselves.

I Thessalonians 3:12 carries the same double emphasis: "And the Lord make you to increase and abound in love one toward another, and toward all men, even as we do toward you." Here the order is reversed. First of all, we are to have love one toward another and then toward all men, but that does not change the double emphasis. Rather, it points up the delicate balance — a balance that is not in practice automatically maintained.

In I John 3:11 (written later than the gospel that bears his name) John says, "For this is the message that you heard from the beginning, that we should love one another." Years after Christ's death, John, in writing the epistle, calls us back to Christ's original command in John 13. Speaking to the church, John in effect says, "Don't forget this . . . Don't forget this. This command was given to us by Christ while he was still on the earth. This is to be your mark."
