People who say they are Christians but who hate other
Christians are deceived. They aren’t really Christians.
1 John 2:9 says – The one who says he is in the light but still hates his fellow Christian is still in the darkness. 1 John 3:15 says – Everyone who hates his fellow Christian is a murderer, and you know that no murderer has eternal life residing in him. 1 John 4:20 says – If anyone says “I love God” and yet hates his fellow Christian, he is a liar, because the one who does not love his fellow Christian whom he has seen cannot love God whom he has not seen.
And people who verbally abuse other people aren’t acting like Christians. 1 Peter 2:23 says that when Jesus was reviled, he did not revile in return.
You can fool yourself, but you can’t hide a hateful heart. When you revile other people, you reveal your heart. But if you will confess your hateful sin, God’s love will heal your hateful heart.
