The Online Course

The PPGR Preaching System is designed to help you save time with a step-by-step guide to creating substantive, redemptive sermons that expound a biblical text, address a problem with the human condition, connect the message explicitly to the cross, and provide relevant, grace-motivated, and Spirit-empowered application.

1:1 Coaching

While the PPGR Preaching System provides a wealth of practical help for taking a step-by-step approach to crafting distinctively redemptive, cross-tethered sermons, I find that pastors are able to master the system much more quickly with personal coaching. If you're interested, let's connect and see if 1:1 coaching could help you.

đź‘‹ Hi, I'm McKay!

I served as a local church pastor and planter for over twenty-six years and understand the unique pain points of a preaching ministry.


For some of us, sermon stress is an ever-present emotional weight.


Every week, we're expected to craft a fresh, focused, well-organized message filled with expository acumen, theological depth, and insightful, relevant, practical application delivered with clarity and energy that keeps folks from looking at the clock.


But we also have leadership meetings, visitor follow-ups, hospital calls, counseling appointments, and more.


And most of us have families who appreciate a bit of our attention, too.


Pastors do far more than preach on Sundays. But we don't do less.


I get it.


I also get what it's like to work on a sermon all week, only to be up at 1:00 am on Saturday night, still struggling with the message.


When I transitioned from preaching to teaching theology and homiletics in seminary, I decided to take the time to create the sermon prep and delivery system I wish I'd had thirty years ago.


Not just a system, but a system that helps pastors save time crafting focused, clear, biblical, redemptive (cross-tethered) messages that result in distinctively grace-motivated, Spirit-empowered application.


Thanks to homiletical influences like Bryan Chapell and Tim Keller, I didn't have to start from scratch. 🙂


In case you're interested, it's called the PPGR Preaching System.


By the way, I've been married to Kristy for 31 years, with whom I have three adult children, 28, 26, and 20. ‌I also hold a B.A. in history/literature, an M.Div., a D.Min in spiritual renewal, and a Ph.D in homiletics. And when I'm not writing or teaching, I love being at home or walking the wooded, creek-crossed trails of the north Georgia mountains.

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.

Galatians
