NEW FREE RESOURCE: A Three-Part Series on Repentance

The Big Difference a Small Preposition Makes

Repentance is a pivotal aspect of doctrine for followers of Jesus. A small misuse of the term, however, could mean a colossal misunderstanding for Christians. It all comes down to the use of a small preposition.

How Getting Busted is Grace in Disguise

Paul wants us to see that every human stands on the same ground as equal sinners deserving the full wrath of the law in the form of divine judgement.


This leads to a HUGE opportunity.

One of the Most Misunderstood Words in the Bible

I have taught on this subject more times than I can count and assumed I knew what I was talking about. But it was twenty years into my marriage before I discovered the shocking truth when the veil was removed with a phone call.

The PPGR Preaching System

All the video and text lessons, downloads, and bonuses are included the updated 5-part, 21-lesson course designed to help you save time preparing sermons that not only are exceptionally clear and focused but also generate practical application from the text that is distinctively grace-motivated and Spirit-empowered (vs moralistic or guilt driven). Print the entire manual or read/watch/listen on any device.

The message of the Bible turns the tables on what we think of religion. Religion says that I am blessed, forgiven and accepted by God based on my obedience and sacrifice. But the Bible teaches that I am blessed, forgiven and accepted not by my obedience and sacrifice, but because of the obedience and sacrifice of someone else who obeys and sacrifices himself in my place.


In this 8-lesson eBook with discussion guide, discover the practical implications of the radical grace that is the gospel.

I Am Not the Christ: Pastoral Identity in View of the Cross

Birthed from a combination of deep theological reflection and twenty-six years of pastoral experience as an assistant pastor, lead pastor, and church planter who served in cities, suburbs, a farming community, and a small college town, I am Not the Christ is full of practical application that aims to give pastors renewed joy in their calling as ambassadors of grace by helping them tether all of life and ministry to the cross of the risen and reigning Jesus.

"Wise, candid, and eminently readable. There is guidance here for every pastor."

- Dr. Dan Doriani, Author and Professor, Covenant Seminary


"The journey McKay describes with much personal reflection will renew the hearts of pastors and bless those whose Savior is the only Christ."

Dr. Bryan Chapell, President Emeritus at Covenant Theological Seminary and author of Christ-Centered Preaching

Facets: Seeing and Savoring the Beauty of God's Grace in Jesus

  • The Beauty of Predestinating Grace
  • The Beauty of Regenerating Grace
  • The Beauty of Justifying Grace
  • The Beauty of Adopting Grace
  • The Beauty of Sanctifying Grace
  • The Beauty of Glorifying Grace


FREE DOWNLOAD | What About Works: Understanding the Relationship Between Faith and Fruit

How do faith, grace, and works relate to one another? Getting this straight is not just a matter of theological importance, but of practical importance; not just for becoming a Christian, but for living as a Christian.


If I am saved by grace alone, then what role do works play in the Christian life? If they don’t save, secure, or sustain me, why should I be at all concerned about whether there is any practical change in my life as a disciple of Jesus?


Good questions! 🙂

The aim of this resource is to help you discover (or maybe rediscover) the spiritual power of moral honesty. Yes, it hurts more than you want, but it unlocks a door to a life of freedom and grace you've always craved.

The Bronze Serpent: Tethering Your Live to the Cross with Scripture-Based Prayer (A 30-Day Devotional Guide)

There are many books on prayer and many books centering on Bible study.


My desire in this effort was to join the two: the Bible and prayer. Therefore, you'll notice that each prayer is also a theological and practical reflection on a particular passage of Scripture. My goal was to let the Bible inform my conversations with God, turning prayer into a dialogue that centers on my need to live completely in dependence upon the grace of God—in view of the cross.

Passion Week: Daily Meditations on the Seven Most Pivotal Days in Human History

If there is one week in the story of humanity upon which the true balance of history (and eternity itself) rests, it is the final week of Jesus' earthly life, culminating in his crucifixion and resurrection. The lessons from these seven days are as instructive and profound for us today as they were in the first century A.D.

👋 Hi, I'm McKay!

After serving over twenty-six years as a local church pastor and church planter, I now teach theology and homiletics, lead the DMin program in Gospel Renewal and Pastoral Leadership, and serve as director of the church planting residency for Metro Atlanta Seminary.


I'm also a writer and content creator with a deep desire to help folks come alive to the wonder, beauty, and transforming power of God's grace by tethering all of life to the cross of the risen and reigning Jesus. ‌ ‌


I've been married to Kristy for 31 years, with whom I have three children, 27, 25, and 19. ‌ ‌With B.A., M.Div., D.Min., and Ph.D. degrees, I really enjoy school. 🤓


When not developing seminary courses, teaching, or writing, I enjoy being at home and exploring the mountains of north Georgia. ‌ ‌
