You can't be a good Christian, while being an unfaithful spouse, a selfish neighbor, or a bad friend. Relationship problems are spiritual problems.
The old saying goes, " If you don't have something good to say, don't say anything at all." Silence is always an option. So is having something good to say.
Romans 1:29-30 has an extreme list of wicked things, like hating God and being a murderer. Do you know what else makes the list? Gossip. If you'd rather talk behind somebody's back than to their face, you've got a problem.
Gossip is a sin. So is murder. Given the choice, I would rather you talk about me than kill me. From our perspective, sins of speech seem minor. But they are not.
Just because you don't see it or think about it doesn't mean the spiritual world doesn't exist. Your life is impacted by unseen realities every day. What would you see if God opened your eyes?
You chase the wrong things, and you will live for the wrong things. in the end, you will have wasted your life. Don't.
