Jesus told His disciples: “By this all men will know that you are my disciples, if you love one another.” John 13:35
In other words: if we show love by our actions the world will notice, they may even stand and applaud.
Now, this “loving one another” was not just some passing comment by Jesus. It became the royal law of the Kingdom. James 2:8 tells us “If you really keep the royal law found in Scripture, ‘Love your neighbor as yourself,’ you are doing right.”
In fact, love was to become such a crucial part of who we are as Christians that Galatians 5 tells us it is THE MARK of the Spirit bearing fruit in our lives.
