A few years ago, I brought a group of young people on a mission trip. As we neared our departure date, the most frequently asked question was, “Is there Wi-Fi?” So just imagine the wails and groans one night when the Wi-Fi was down!

Many of us become anxious when we’re separated from our smartphones. And when we have our iPhones or Androids in our hands, we can be fixated on our screens.

Like all good things common to man, Wi-Fi and all that it allows us to access can become either a distraction or a blessing. It depends on what we do with it. In Proverbs we read, “A wise person is hungry for knowledge, while the fool feeds on trash” (Proverbs 15:14). In our daily food choices, a healthy diet takes discipline and may not be as sweet or as enticing as junk food. So it’s also important that we take care in what we feed on as we browse the web.

What might that look like? It can be as simple as reviewing who you follow on Instagram. Do the things they post bring “joy to those with no sense” or encourage sensible living? (Proverbs 15:21). Do your Facebook posts or Snapchat messages reflect “the heart of the godly [who think] carefully before speaking” or the “mouth of the wicked [that] overflows with evil words”? (Proverbs 15:28).

The words of Proverbs 15:14 make it plain: We are what we eat . . . and what we do and view online. Feed on wisdom, and you’re more likely to become wise. Feed on trash, and you’re headed for trouble.

As we yield to the work of the Holy Spirit, we can fill our minds and mobile device screens with things that are “true, and honorable, and right, and pure, and lovely, and admirable” (Philippians 4:8). By God’s wisdom, we can make good choices online and in all of life.
