According to Jesus, what is the distinguishing mark of a Christian? Is it faith? Surely, that which God gives, and through which we are his, is the distinguishing mark? Or, is it hope? Surely, that which rests squarely on God’s provision in Christ, and in which we are to abound, is the distinguishing mark? But as essential as faith is and as important as hope is, shortly before the conclusion of his earthly ministry, Jesus said to his disciples, “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). Echoing Jesus’ command and reinforcing its distinction, Paul confirms, “So now faith, hope, and love abide, these three; but the greatest of these is love” (1 Cor. 13:13).
