31 When he had gone out, Jesus said, “Now is the Son of Man glorified, and God is glorified in him. 32 If God is glorified in him, God will also glorify him in himself, and glorify him at once. 33 Little children, yet a little while I am with you. You will seek me, and just as I said to the Jews, so now I also say to you, ‘Where I am going you cannot come.’ 34 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. 35 By this all people will know that you are my disciples, if you have love for one another.” – John 13:31-35
Jesus said, “By this all people will know that you are my disciples, if you have love for one another” (John 13:35). Loving one another in the body of Christ has many benefits. Two that regularly come to mind are the glory it gives to God and the way it affects the church. However, one of the primary benefits of loving one another is what it declares before a watching world. One of our most potent instruments we have for effective evangelism is Christians loving each other well. I am “living” proof.
As a freshman college student and self-declared atheist, I attended a campus Christian fellowship to fulfill a promise to a Christian friend. I only had the intention to go once. It was merely duty and upholding my word, nothing more. I went begrudgingly, but I went. My life was never the same.
I walked into a room full of Christians and was struck by what I observed. Here was a diverse group. They were from every walk of life. I remember scanning the room and labeling people in my mind, “There is a jock, over there is a geek, and walking in the door is a boy scout.” But what struck me was that they were together. They weren’t just together in the same room, they were together in every sense of the word. They were actually talking with each other and genuinely seemed happy to be together. There didn’t seem to be division. Even in my atheist mind, I knew what I was seeing: they loved one another.
I had no categories for this, so I kept returning to find out why they had love like this for one another. Over the course of a few months I found the answer, or more accurately stated, the answer found me.
One of the best evangelism programs you can start at your church is to pursue loving one another well. At some point they will have to hear the gospel proclaimed from your lips or the pulpit, but that “strange love” will set the table before them. People will know that you are His disciples, because it is a shocking love. It has a gravitational attraction, because it is a love that is foreign to this world. A love that the inquirer, if seeking an answer, will find comes from heaven.
