From Cain and Abel to the book of Revelation, these 30 questions and scripture-grounded answers cover the essential stories, doctrines, and teachings every Christian should understand.
Key Verses
Matthew 28:19-20
"Go therefore and make disciples of all the nations, baptizing them... teaching them to observe all things that I have commanded you."
2 Timothy 3:16-17
"All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness."
Old Testament Essentials
Key questions include: Who was Cain and why did he kill Abel? (Genesis 4 — jealousy over God's acceptance of offerings). What was the Great Flood? (Genesis 6-7 — divine judgment on human wickedness, with Noah's family preserved). What is the significance of the Abrahamic covenant? (Genesis 12 — the foundation of God's redemptive plan).
New Testament Foundations
Essential questions: Who were the 12 apostles? Why did Jesus speak in parables? What is the Great Commission? (Matthew 28:18-20). What happened at Pentecost? (Acts 2 — the Holy Spirit poured out, the church born). These answers form the narrative backbone of Christian faith.
Doctrine and Theology
Christians should know: What is justification by faith? (Romans 3-5). What is the Trinity? What does baptism signify? What is the Lord's Supper? Understanding these doctrines transforms Sunday attendance into informed, heartfelt worship.
Practical Application
Bible literacy is not academic exercise — it shapes how we live. Knowing the stories of Joseph, Ruth, Daniel, and Paul gives us models of faithfulness. Knowing the promises of Romans 8 and Revelation 21-22 gives us hope in every trial.
