On-the-Go Devotional: 200 Devotions for Teens, by Leslie Hudson, is a great book to get teens into God’s Word.
No matter busy they are, these short, and to the point devotionals are organized in an appealing and user-friendly way.
Each day is focused on a topic, and includes a verse of Scripture, explaining the passage and how to apply to everyday life. It also gives teens actions steps for that day.
Topics include, for example: humility, worry, joy, freedom, faith, hope, friends, family, salvation, etc.
It only takes one to two minutes to read, but is quality content, highly valuable for teens today.
I highly recommend this devotional for any teen!
