What Words Are Swear Words?

What exactly is a swear word, and why does it matter?

God cares about our speech—there are many verses in the Bible dedicated to our mouths and what comes out of them (which ultimately is a reflection of what comes out of our hearts). For example:

Let no unwholesome word proceed from your mouth, but only such a word as is good for building up what is needed, so that it will give grace to those who hear. (Ephesians 4:29)

Let your words always be with grace, seasoned with salt, so that you will know how you should answer each person. (Colossians 4:6)

And the tongue is a fire, the very world of unrighteousness; the tongue is set among our members as that which defiles the entire body, and sets on fire the course of our existence, and is set on fire by hell. (James 3:6)

It is not what enters into the mouth that defiles the man, but what proceeds out of the mouth, this defiles the man. (Matthew 15:11)

Let there be no filthiness nor foolish talk nor crude joking, which are out of place, but instead let there be thanksgiving. (Ephesians 5:4 ESV)

And there are many more!

So how should Christians build a biblical worldview regarding their words and everyday speech? Well, I recently shared my thoughts and some Scripture that directly applies to this issue in a YouTube video for my channel. You can watch that below (and be sure to subscribe to catch my other videos):

Christians must have a biblical worldview in all areas and make sure we’re never just absorbing thought or speech patterns from the godless culture around us.

Yes, Christians must have a biblical worldview in all areas and make sure we’re never just absorbing thought or speech patterns from the godless culture around us.

By the way, I have many more interesting videos in the pipeline that will be added to my YouTube channel, so make sure you subscribe.

Thanks for stopping by and thanks for praying,
