We may have the purest doctrine, we may have dynamic preaching and teaching, we may have beautiful music and worship, we may have ambitious programs of mission and outreach, we may have well-maintained facilities. I believe that this is the chief reason that the Church seems to have such little impact in today's world. It's not for lack of words or books or advertising or communication. It's for lack of love. Without genuine Christian love for one another, no one will know that we are disciples of Jesus, no matter what we say we believe.
Love makes faith visible.
You can talk all you wish about your faith. Faith is between you and God. By your love, the world will see your faith, and recognize that you are disciples of Jesus. This may be a new commandment, but it is still a command from the Lord. We must acknowledge, each of us in his or her own way, that we have not loved one another as Christ has loved us.
