Welcome to

Helping People Come Alive to the Wonder and Transforming Power of God's Grace by Living All of Life in View of the Cross



The blog is the overflow of my preaching, teaching, and writing ministry. Posts often follow a series but sometimes are current thoughts about what God is doing in me at the time. My goal is to be helpful, clear, and accessible so that what is helping me can help you, too. I'd love to have you tag along for the journey.

For example, every church and school would love to provide training for their teachers. But training is hard, requiring time and a lot of coordination. Your turn-key solution is in development, The Spurgeon Teaching Method, a cross-centered video training course that is the product of 25-years of teaching... and teaching teachers to teach.

Coming Spring 2019!

Designed to help Bible teachers "tie and tether" every lesson to the cross of Jesus, providing Bible study leaders, Christian educators, and parents with a distinctive "grace-centered" model for living all of life.


The story of redemption is the story of the Bible and of all history. The epicenter of that story is the cross of Jesus, where he becomes a substitute for sinners, taking the place of judgement so that we can be forgiven and free. 

This cross-centered theology is the frawework from which all articles, ebooks, webinars, and courses are  created at www.MCKAYCASTON.com.

Substitution is beautifully depicted by C.S. Lewis in his classic, The Lion, the Witch and the Wardrobe, where Aslan is slain upon a stone table in the place of Edmund, the traitor. When Lucy and Susan discover that stone table cracked and that Aslan is not lying there dead as he had been, they come to realize that the curse upon Narnia has been broken.

It is by simple, close, and searching views of the cross of Christ that the Spirit most effectually sanctifies the believer.

-  Octavius Winslow

I did not come with eloquence or human wisdom as I proclaimed to you the testimony about God.  I resolved to know nothing while I was with you except Jesus Christ and him crucified.

- Paul the Apostle, 2 Cor. 2

I wish that our ministry--and mine especially--would be tied and tethered to the cross.  I would have no other subject to set before you but Jesus only.

- Charles H. Spurgeon

It is hard to miss the profound Christological imagery Lewis has woven into the story, whether intentionally or not.

Here is how the scene plays out as the sisters hear a deafeningly loud sound of the stone cracking-a crack that ran from end to end.

"Who's done it?" cried Susan. "What does it mean? Is it more magic?"

"Yes!" said a great voice from behind their backs. "It is more magic." They looked round. There, shining in the sunrise, larger than they had seen him before, shaking his mane (for it had apparently grown again) stood Aslan himself. "Oh, Aslan!" cried both the children, staring up at him, almost as much frightened as they were glad...."But what does it all mean?" asked Susan when they were somewhat calmer.

"It means," said Aslan, "that though the Witch knew the Deep Magic, there is a magic deeper still which she did not know. Her knowledge goes back only to the dawn of time. But if she could have looked a little further back, into the stillness and the darkness before Time dawned, she would have read there a different incantation. She would have known that when a willing victim who had committed no treachery was killed in a traitor's stead, the Table would crack and Death itself would start working backward."

Integrating cross-centered theology, identity, and transformation, our aim is to produce resources that reveal how the curse of sin has been broken, not by a Lion upon a table, but by Jesus upon a cross, our substitute in life and death.



Gospel-Centered Theology

At the heart of all of Scripture is the redemptive message of God's saving grace to sinners in Jesus. Theologically, we call this justification, which is the hub of the theological wheel to which every passage and doctrine is connected. This grace message is the oak from which every acorn of biblical texts falls and must be related in order to be properly understood and applied. Or as Martin Luther said, justification is the doctrine upon which the church stands or falls. This is why we are committed to gospel-centered theology. 


Gospel-Focused Identity

Every human either will find his or her core identity in a self-achieved righteousness (or the lack of it) or in a gift-received righteousness. We will functionally live as spiritual orphans trying to make a life and name for ourselves, or we will live like adopted and beloved sons and daughters, with all the freedom, peace, hope, and joy that flows from such an identity. The implications are manifold and wide-ranging, touching on practically every area of life.  This is why we are committed to gospel-focused identity.


Gospel-Empowered Transformation

What now? Should I expect to experience spiritual change in my life? If so, how does that takes place? What is my role in the process?  As Jesus says in John 15, "No one can produce good fruit apart from me." Practically speaking, this means that we experience the fruit of the Spirit as we consciously abide in the Vine of Jesus' imputed gift-righteousness. As the Spirit fills us like sap through a vine into a branch, we receive new motives and a new ability to manifest the new life of love, peace, patience, kindness, etc. This is why we are committed to gospel-empowered transformation.

I began MCKAYCASTON.com in 2006 as a place to think out loud and post pics of my family. Yes, my blogging pre-dates the Facebook, Twitter, and Instagram revolution. :) 

Over time, the blog became a space to share content as I began to morph from a pastor who preaches and teaches to a pastor who writes. 

Eventually, I discovered that the reason I love to share the content I create is that I have a deep longing to help people with practical insight and usable tools. Specifically, I want to help people come alive to the beauty, wonder, and transforming power of the gospel by living all of life in view of the cross, helping us to abide in Jesus as our perfect and only righteousness. 

This is why www.MCKAYCASTON.com exists and why I think that you will like being part of this online community. You just might come alive the grace of God in Jesus! :) 

By the way, I'd love to give you access to my growing library of free resources (ebooks, Bible studies with discussion guides, lists, etc.). Click below for lifetime access.

Here is my official "back of the book jacket" bio.

With 25-years of teaching experience as a senior pastor, church planter, college pastor, singles pastor, education pastor as well as seminary professor of hermeneutics, homiletics, theology, and Greek, Dr. McKay Caston's passion is to help people come alive to the wonder, beauty, and transforming power of the gospel by living all of life in view of the cross as they abide by faith in the perfect righteousness of Jesus. 

McKay ministers as Founding and Lead Pastor for Creekstone Church in Dahlonega, GA, and teaches  on the faculty of Metro Atlanta Seminary. 

When not preparing weekly sermons for Creekstone, writing, or spending time with his family and friends, he enjoys exploring the Appalachian Mountains of North Georgia. He and his wife, Kristy, have three children, 23, 20, and 15.
