“By this all men will know that you are My disciples, if you have love for one another.” John 13:35
Jesus wasn’t just talking about having nice thoughts toward others, which no one else can see. He was talking about love that can be seen. It stems from the heart, but it’s seen in outward actions.
Have you ever thought about the diversity among Jesus’ apostles? He chose Simon the Zealot. Zealots were a radical political group that used intrigue, violence, force, and deception. They refused to pay taxes and they attacked and murdered government officials, especially the hated tax collectors.
And then He chose Matthew, the tax-collector! The tax-collectors had sold their souls to Rome. They milked the Jewish people of their money in order to line their own pockets.
You could not have put two men of more diverse backgrounds into the same group if you had tried! These are the men that Jesus is telling to love one another!
The caring aspect of love means that we should never be calloused or rude. Love is kind.
