Believe - What Should I Know? (small printing error)

The Bible Tells Us What to Believe. But Do You Know What That Is?

The Bible is not just a collection of ancient stories. It is God’s own Word — and it tells us what is true about him, about ourselves, about life, and about what lies beyond this life. These are not small questions. They are the most important questions any human being can ask. And the answers, it turns out, are not as complicated as they might seem.

In Believe: What Should I Know?, Mike McKinley offers new and growing Christians a warm, clear, and genuinely accessible breakdown of the essential beliefs of the Christian faith. Christians have sometimes surrounded these truths with complicated theological vocabulary — words that can feel intimidating or impenetrable to someone newer to the faith. McKinley cuts through the complexity without losing the substance, presenting everything a new Christian needs to know about what the Bible teaches in a way that is easy to understand, easy to remember, and deeply encouraging.

This is a book that takes doctrine seriously and makes it accessible — because what we believe matters, and every Christian deserves to understand it.

What This Book Covers

Mike McKinley works through the essential beliefs of the Christian faith in a clear, logical, and accessible way:

What the Bible is — Why Scripture is not just an ancient religious text but the living Word of God, and why it is the foundation for everything Christians believe
Who God is — The nature and character of God: Father, Son, and Holy Spirit, and what the doctrine of the Trinity means for everyday Christian life
Who we are — What the Bible teaches about human beings: made in God’s image, fallen in sin, and in need of rescue
What Jesus did — The person and work of Christ: his incarnation, his perfect life, his atoning death, and his bodily resurrection
What salvation is — How sinners are rescued by grace through faith, and what it means to be justified, adopted, and indwelt by the Holy Spirit
What the church is — Why believers belong together in a local community and what that community is for
What happens after this life — What the Bible teaches about death, resurrection, judgment, and the new creation
