Read John 13:31-38
[Jesus said] “Your love for one another will prove to the world that you are my disciples.” – John 13:35 (NLT)
We are not very lovable, and we are not willing to love others, at least not the sacrificial way Jesus intends, except by the grace of God. So our love for others will be a living demonstration of the power of God at work within us. It is also a way we can monitor our own closeness to God; as we find our love diminishing, we can know that it is time to reconnect to God so that more of His grace can flow to and through us.
