And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself. And he said unto him, Thou hast answered right: this do, and thou shalt live.
We are to love God with all that we are and all that we have. One way to show our love for God is to love others--everyone. We do not need to love their sin, but we should love them enough to care about their eternity.
