Love that comes from sacrifice, and through the power of the Holy Spirit. Jesus showed us how to sacrifice, and he sent the Holy Spirit after he left, so that we might be empowered to Love in this way.

A new commandment I give to you, that you love one another, even as I have loved you, that you also love one another. John 13:34 NASB https://bible.com/bible/100/jhn.13.34.NASB
