Over the past year, I've had the opportunity to write a few articles for the Unlocked teen devotionals. If you're familiar with Keys For Kids, Unlocked is the same ministry, just the teen branch.
The devotionals are available online, in print, or as audio, and they're always looking for new writers. If you're interested in submitting some articles to them, it's super easy to do it here. https://unlocked.org/writers-guidelines/
