We learn that the true spirit of Christmas involves love. We see God’s love for us in the birth of His Son. We also see the proof of God’s love for us through His Son’s death. Just as God has loved us in a sacrificial way, so we should love one another. In fact, John says if we don’t love one another in this way we haven’t really experienced God’s love. We learn how and why we should practice this Christmas spirit of love.
