When Jesus offers the command to love our neighbor as ourselves, He is not only asking us to be kind to others, He is also reminding us of our selfishness.
Mark 12:30-31 And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’ The second is this: You shall love your neighbor as yourself.’ There is no other commandment greater than these.”
After all, God is love (1 John 4:8), and, when presented with His definition, we clearly fall short, but still see the target to point toward.
1 Corinthians 13:4-8a Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things. Love never ends.
