1 John 4:20-21
If anyone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot love God whom he has not seen. And this commandment we have from him: whoever loves God must also love his brother.

This verse hits us with a stunningly simple, yet profound, test of our spiritual reality: If you claim to love the unseen God, but can't show love to the people you actually see every day, your claim is hollow. John flips our common understanding, showing that genuine love for God isn't a feeling you say, it's a practice you show to those right in front of you.
John has just spent the chapter urging believers to test the spirits and recognize that God's Spirit is in those who confess Jesus as Christ come in the flesh. Now, he directly confronts the idea that one can claim to love God without demonstrating that love in their relationships with fellow believers. If you can't love the people you physically see and interact with, your professed love for the unseen God is hollow and untrue.
We hear a lot about loving God, but how do we know if it's real? This verse gives us a surprising test.
John lays out a straightforward principle: genuine love for God isn't just a feeling or a statement; it has to show up in our actions towards others. If you claim to love the unseen God but mistreat or ignore the brother or sister you can see, there's a disconnect. It’s like saying you love the ocean but refuse to go near the water. The love for God that John describes is tangible, flowing from our hearts and impacting our relationships.
Why is it easier to claim love for God than for the person next door? This verse reveals a critical spiritual reality.
John points out the inherent challenge of loving someone you’ve never seen (God) when it’s difficult to love someone you have seen (your brother or sister in faith). God is spirit, infinite, and beyond our full comprehension. Our brothers and sisters, however, are tangible. They have needs, flaws, and personalities we interact with daily. If our love fails to bridge the gap to the visible, imperfect people around us, it raises serious questions about whether we truly grasp or cherish the invisible, perfect God.
