The apostle John, "the disciple of love," recorded the words of our Lord, saying, "A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another" (Jn. 13:34). Jesus proved His love by teaching these men and by His willing sacrifice for sin on the cruel cross. By having this sacrificial, self-denying love, His disciples would be identified as belonging to the Lord. This love was to distinguish them from the world, who lived in the "lust of the eyes, the lust of the flesh, and the pride of life" (I Jn. 2:15-17). Jesus was about to leave the apostles, and He knew that the great work on which they were about to embark and accomplish in the world of carrying the Gospel to all nations would demand their love for one another as well as the lost (Mk. 16:15-16). Love in the Bible is expressed in concern and interest for others. Today, we are to have concern and interest in other Christians, the Bible, the church, in teaching the lost, and in upholding and transmitting the Truth to the future. The work they had to do has been passed on to all Christians today (Mt. 28:20; II Tim. 2:2).
The glue that holds the people of God together today is love. "Blest be the tie that binds our hearts in Christian love"! Some in the religious world want to be known by wearing no makeup, long hair in a bun, plain dress, etc. These are not the marks of the disciples of the Lord. But, love is that badge of discipleship. Let each of us "adorn the doctrine of God our Saviour in all things" (Tit. 2:10).
