And the second, like it, is this: ‘You shall love your neighbour as yourself.’ There is no other commandment greater than these. Mark 12:31

Christ prayed for his disciples “that they all may be one; as thou, Father, art in me, and I in thee that they also may be one in us; that the world may believe that thou hast sent me.” The unity of believers is to be an evidence to the world of the divine power and mission of Christ. This should be the mighty argument to convince the world that Christ is the Son of God, the Redeemer of fallen man. The love existing between believers is to be similar to the love existing between the Father and the Son. And this love in the soul is the evidence of the indwelling of the Holy Spirit. We are to love God supremely, and our neighbours as ourselves. It is in the lack of this love that thousands fail, and are found transgressors of the law. Supreme love for God will lead to love for our fellow-men, and the commandment of Christ is, “Love one another as I have loved you,” “By this shall all men know that ye are my disciples, if ye have love one for another.” We cannot have this love unless Jesus is abiding in the heart by living faith. The very unity of disciples, the love manifested one for another, will be evidence to the world that God has sent his Son into the world as its Redeemer. This unity and love will exist wherever the Spirit of the Lord abides; heart will be bound to heart, and works of righteousness will appear in the daily life. {The Signs of the Times 1891}
