My passion is creating cross-tethered resources that help folks come alive to the wonder, beauty, and transforming power of God's grace in the risen and reigning Jesus.

Available Spring 2024

There is a lot of confusion concerning the relationship between justification and sanctification, especially how it relates to preaching moral imperatives. Is there a biblical model that gives us a hint for preaching in a way that does not conflate nor separate the justifying and sanctifying grace of God? Sanctifying Grace takes a deep dive into the theological and practical issues at stake, helping those who preach gain greater confidence in the message of the cross to save and sanctify.

Just like overused tires may get worn and lose their gripping power, words may become so overused that they no longer retain the tread with which they were originally created.

The word love is like that. So is awesome. Not to mention the word gospel.

What does it mean for a sermon to be genuinely gospel-centered?

In this ebook, we take a look at six important considerations.

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

The description “one size fits all” is rarely true.

It doesn’t work with gloves, shoes, shirts, or pants. Even caps, wristwatches, belts, and other accessories need some adjustment for a proper fit.

The same is true with pastoral ministry. This is especially important for young pastors to grasp, as there are pastoral molds into which they will be expected to conform. Sometimes, these molds are more culturally constructed than biblical, more burdensome than liberating. They’re ill-fitting clothes.

In this easy-to-read, formatted for digital reading ebook, Help for Pastors Who Are Feeling the Weight of Expectations shows us that we don't have to wear Saul's armor. The gospel paves a better way.

FREE DOWNLOAD! The Grade Exchange

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.

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. 🙂 And only 14 pages!

FREE DOWNLOAD! 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 project 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. The goal is to let the Bible inform our conversations with God, turning prayer into a dialogue that centers on our need to live completely in dependence upon the grace of God—in view of the cross.

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.
