Discover the greatest treasure of all: A life with Jesus! Kids Discipleship Quest is an interactive Bible discipleship app designed to help children know God's Word, understand God's Word, and live God's Word. More than a Bible memory app, Kids Discipleship Quest takes children on an exciting journey through Scripture, helping them build a lifelong relationship with Jesus. Each Bible study is divided into weekly Dig Sites, with every Dig Site designed to be completed as a one-week expedition. Through short Daily Digs (about 10–15 minutes each), children develop consistent Bible habits while exploring God's Word in engaging and meaningful ways. Your Weekly Expedition Includes: Hide It - Watch engaging Bible memory videos that introduce each week's Scripture passage and begin the journey of hiding God's Word in your heart. Read It - Read or listen to the Bible passage while following along in Scripture to better understand God's Word. Seek Him - Discover what the passage teaches about God through kid-friendly devotionals, reflection questions, and biblical insights that help children grow in their faith. Follow Him - Complete practical Discipleship Missions that encourage children to put God's Word into action and become more like Jesus throughout the week. Quiz Me - Build confidence with fun review questions that reinforce Bible facts and key concepts. Challenge Me - Put your knowledge to the test with increasingly challenging quizzes and Scripture memory activities that help move God's Word from short-term memory to long-term retention. Explorer Zone - Continue the adventure with interactive Bible games and activities that reinforce important biblical concepts such as the Ten Plagues, Ten Commandments, Tabernacle and more. Base Camp – Access all Dig Sites in one place to make reviewing quick and easy! Watch your discipleship journey grow as you complete each expedition. Designed for Growing Disciples: Kids Discipleship Quest encourages children to build lifelong habits of spending time with God. Rather than rewarding only high scores, the app celebrates consistency, faithfulness, and spiritual growth through daily engagement with Scripture.
