1 John 4:20-21 New King James Version (NKJV)
Obedience by Faith
20 If someone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen, [a]how can he love God whom he has not seen? 21 And this commandment we have from Him: that he who loves God must love his brother also.
1 John 4:20-21 New International Version (NIV)
20 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. 21 And he has given us this command: Anyone who loves God must also love their brother and sister.
