Have you ever walked out of a church service feeling like you were handed a complex manual for a machine you don’t own? We often crave spiritual depth but find ourselves drowning in “abstruse disquisitions”—those fancy, high-level theological debates that seem to have very little to do with the fact that we were impatient with our kids this morning or are currently worried about our bank accounts. There is a common curiosity among us: is it possible to be deeply Reformed, holding fast to the Westminster Standards, without being totally disconnected from the kitchen table? In his collection of Practical Sermons, the first professor of Princeton Seminary, Archibald Alexander, proves that the highest truths are actually the most useful. He didn’t write these for other professors; he wrote them for families to read together when they couldn’t make it to a church service.
Alexander was a man who understood that a sermon isn’t a performance to be admired, but a message to be used. As a pastor who looks to our Confession for guidance, I find his approach refreshing. He doesn’t offer “life hacks” but rather shows how the grand doctrines of grace actually work when the rubber meets the road. Here are the most impactful takeaways from this shepherd’s heart.
Assurance is Found in the Doing, Not Just the Thinking
One of the most surprising points Alexander makes right at the start is that if you want to be sure that the Bible is true, you have to start living like it is. We often think that we need to reach a state of 100% intellectual certainty before we can truly obey. Alexander flips the script. He argues that obedience to Christ actually produces assurance of the truth. When you possession a state of mind that chooses to obey God, the “excellency of the truth” becomes visible to you in a way that mere study can never produce.
This is a vital reflection for the person struggling with doubt. Alexander explains that a blind man can be convinced the sun exists because he feels the warmth, but he still doesn’t see it. In the same way, unrenewed men might be convinced by logic, but the humble believer sees the beauty of Christ through the act of following Him. The light of the gospel shines brightest on those who are walking the path.
“If any man possess that state of mind which will prompt and lead him to choose the service of God, and determine to obey Him, he will be at no loss respecting the truth of my doctrine; for he will have such a view of the excellency of the truth which I deliver… that he will, at once, be persuaded of the divine origin of the plan of redemption.”
Your Pride is a Literal Blindfold
Alexander spends a significant amount of time on why it is so incredibly hard for us to see our own faults. We all have that one friend who can spot a flaw in everyone else but is totally oblivious to their own issues—but Alexander reminds us that, spiritually speaking, we are all that friend. He notes that pride and self-love create a “false medium” through which we view ourselves. It isn’t just that we lie to others; we actually successfully lie to ourselves.
This analysis is insightful because it explains why so many “moral” people feel no need for a Savior. They are looking at themselves through a mirror of their own making. Alexander argues that the closer we get to the light of God’s law, the more “secret faults” we will find. It is like letting a ray of light into a dark, dusty room; the light doesn’t create the dust, it just makes it visible. If you think you are growing in grace but don’t feel more sinful than you used to, you might actually be standing in the dark.
“The heart of every man is by nature deceitful; yea, the most deceitful of all things. Mankind know not their ownselves. They have not proved themselves by the test of God’s word; and, therefore, they know not what manner of spirit they are of.”
God Leads the Blind by Paths They Don’t Recognize
Perhaps the most comforting takeaway in the entire book is Alexander’s reflection on how God actually conducts our spiritual progress. We often have a “blueprint” in our heads of what a religious life should look like: steady growth, constant joy, and clear directions. But Alexander points out that God often brings the blind “by a way that they knew not.” He describes the Christian experience as one of unexpected turns, where the soul feels like it is recrossing the same territory or even sliding backward.
This point is essential for the layperson who feels like a failure because they are currently in a “dark” season. Alexander explains that God purposefully allows us to feel our own weakness and the strength of our remaining sin. He does this to empty us of self-confidence so that we might finally lean entirely on the “all-power” of Christ. What feels like a detour to us is often the most direct route to humility.
Spiritual Love is a Fire That Needs Fuel
In an age where we treat love like an unpredictable emotion that just “happens” to us, Alexander treats the love of God as a fire that must be intentionally tended. He warns us that we are prone to lose the fervor of our “first love” and sink into a state of spiritual sleep. Sloth is the great enemy of the soul. He argues that we must “keep ourselves in the love of God” by actively shunning things that damp the fire—like worldly ambition or the neglect of the closet—and by frequently meditating on the superlative excellence of Christ.
This reflection provides a much-needed push for the modern Christian. We shouldn’t sit around waiting for a “feeling” of love to return. Instead, we are called to use the means of grace—reading, praying, and social worship—to recruit our strength. Alexander reminds us that while God is the one who gives the increase, the husbandman must still plow and sow.
“A healthy state of piety is always a growing state; that child which grows not at all must be sickly. If we would enjoy spiritual comfort, we must be in a thriving condition.”
Why You Should Read This Book
Archibald Alexander’s Practical Sermons is a necessary read because it bridges the gap between the heavy-duty theology of the Westminster Confession and the messy reality of your daily life. It is rare to find a book that respects your intelligence while speaking directly to your heart’s anxieties. Alexander doesn’t just tell you what to believe; he shows you what those beliefs look like when you are sick, when you are grieving, or when you are simply tired of the world.
