1 John 4:20 - 21 (NIV)

Whoever claims to love God yet hates a brother or sister is a liar. For whoever does not love their brother and sister, whom they have seen, cannot love God, whom they have not seen. And he has given us this command: Anyone who loves God must also love their brother and sister.

Romans 5:5b (ESV)

God's love has been poured into our hearts through the Holy Spirit who has been given to us.
