Inspired by Christian Posture: Walk Tall, Stand Straight in a Crooked World—Core Doctrines by David Parker Mitchell

 

We live in a world that really does tilt on its axis. As culture changes, morality is often redefined. How do we stand firm when everything around us is bending? The solution, as David Parker Mitchell says in Christian Posture, is to develop a spiritual posture that is upright and straight, based upon God’s truth, not swayed by the currents of the day.

Posture of the body is important, but posture of the spirit is even more so. Just as a strong core supports the body, a firm understanding of biblical truth supports the Christian life. Hebrews 6 talks about “the principles of the doctrine of Christ” as fundamentals to be learned before advancing to higher maturity. These fundamental doctrines, like knowing exactly Who Christ claimed to be, understanding repentance, baptism, eternal judgment, faith, resurrection, and the security of the believer, are what grant us stability and strength. Without these doctrines, we flex easily under the stress of the winds of philosophy from the culture. With them we stand upright because the Word of God is firm.

The world is bent because it is fallen. Since the day that Adam and Eve opted for their own path in the garden, the cosmos itself has been crooked. Paul reminds us in Romans 8:22 that “the whole creation groaneth and travaileth in pain together until now.” The world, left to itself, cannot stand straight. It breaks down beneath the weight of its own flaws, due to the original sin of mankind.

This is the reason why Christians cannot turn to culture for their compass. What is honored today will be condemned tomorrow. What will feel popular today will turn out to be destructive later, when the standard shifts, the ones who abide by it will always bend with it.

It takes both conviction and humbleness to stand upright in a crooked world. Conviction is the assurance of holding on to what God has shown us, even if it costs us. We are to “rightly divide the word of truth” (2 Timothy 2:15), as Paul instructed Timothy. That involves being familiar enough with Scripture to distinguish what is eternal and what is temporal, what is in line with the whole of Scripture and is therefore foundational, and what is out of context.

Humility is remembering that holding ourselves up straight is not standing proudly. We do not stand tall to impress the world, but to honor Christ. The posture is a posture of confidence, but also a posture of surrender, standing tall because we lean on Him, not on ourselves.

The good news is that we do not stand alone. The church of history has been a fellowship of believers challenging each other to stay upright. From the Apostolic Age to the modern era, loyal men and women have opposed accommodation, bearing witness to the truth of God that does not yield even when all else yields. Their testimony emboldens us to do the same.

The world can bend, but the Christian is to stand upright. Christian Posture teaches us that the key to standing straight is to strengthen our spiritual core through personal Bible study and faithfully walking hand in hand with Christ. In a bent world, that posture is not only possible, it is crucial.

The first few decades of the Christian church are somewhat captivating. Referred to as the “Apostolic Age,” these years spanned from the ministry of Jesus and His Apostles up to the time of the death of the final Apostle. It was a distinctive and transitional phase, encompassing remarkable events, miracles, signs, and open revelation, that created something entirely new. But to grasp this age takes more than interest; it also takes cautious interpretation. How we define “then” and “now” determines how we approach Scripture and live our faith today.

During the Apostolic Age, the church was developing its foundation. The news of Christ was recent, and God attested to it with signs and wonders. The Acts records for us healings, speaking in tongues, and miraculous deliverances. These were not random shows. They were God’s means of attesting that the gospel bore divine authority.

The Apostles themselves had a special role. They were witnesses to Christ’s resurrection, personally chosen by Him, and empowered with authority that no one has borne since. They preached the gospel and also set the stage for what would eventually become the New Testament. Back then, revelation was being penned down. One requirement to be an Apostle was that he must have walked with Christ on this earth and witnessed the resurrected Christ; therefore, there are no valid Apostles today.

Fast forward two millennia. We are no longer living in the same period of transition. Scripture is completed, the Apostles are in heaven, and the church has entered into what David Parker Mitchell refers to as the “mature church age.” This is to say that although the Acts lessons continue to inspire and teach us, we need to take care not to think that all the methods used by the Apostles are good for mature church methodology and practice. The “sign gifts” that occurred early in church history were never intended to be done over and over again. They were “for a season.”

Today, the chief manner in which God addresses His people is through His written Word. Rather than anticipating visions or private revelations, we turn to the Bible, where Christ has already spoken to all of us. As Hebrews states, “God…hath in these last days spoken unto us by his Son” (Hebrews 1:1–2). The work of the church now is not to establish new foundations but to build soundly on the one that is already laid by God, through the first-century Apostles and prophets.

So what does this difference imply for us? First, it requires us to “rightly divide the Word of Truth.” Misapplying passages from a transitional period to the current era can cause confusion. For instance, some people today demand that the miraculous sign gifts persist precisely as they did in Acts. But Pastor Mitchell observes that even the early church fathers, several hundred years later, no longer saw these gifts functioning.

Second, it calls us to appreciate the maturity of our time. We possess the complete canon of Scripture, the witness of centuries of devout believers, the instructions of famous church historians, and the indwelling Spirit that leads us into truth. The greatest advantage we have over the first-century Christians is the completed canon, which the Holy Spirit sheds light upon as we read.

The Apostolic Age was magnificent, but it was only a brief one. Its mission was to get the church started and validate the gospel message. Today, as a new generation of believers living in the mature church age, we are challenged to stand firm on what has already been entrusted to us. We do not need to redo the past. We must live boldly in the present, cling to Christ and His Word, and be the salt and light of the world.

The journey of faith starts with elementary truths: Jesus is the Savior, God is faithful, and the Spirit leads us. These fundamentals make a difference, but they aren’t intended to be the stopping point. Believers are as much encouraged to grow deeper in faith, wisdom, and spiritual insight as children are encouraged to mature.

Growth, however, is tricky. If we are not thoughtful and proceed without direction, we will be led astray by good-sounding but faulty teachings. If we don’t grow at all, we are shallow and unprepared to deal with difficult issues. The solution is balance—gradually growing while still being anchored in what we originally believed.

Why Maturity Matters

Maturity provides stability. A mature Christian can withstand doubts, questions, and pressures and not collapse. Not that we have all our answers, but that we are grounded in the Word of God so we can test what we hear and cling to what is true.

For instance, when faced with conflicting messages, an immature faith will freak out. But maturity provides us with confidence to take a step back, open the Bible, and look for God’s wisdom. This way, maturity safeguards us from being influenced by every new trend or idea.

How to Grow with Balance

We don’t get growth overnight but through habits practiced daily: prayer, reading Scripture, and being around a fellowship of believers. These small choices add up and over time strengthen us, just like how exercise strengthens the body. With practice, we can walk more confidently and stand up straighter, even when life gets wobbly.

When it comes to balance, it is not always easy because it requires humility. To be a learner, teachable, and acknowledge we do not know keeps pride away. Ironically, humility itself is one of the most obvious indicators of maturity.

In Christian Posture: Walk Tall, Stand Straight in a Crooked World — Core Doctrines, Vol. I & II, David Parker Mitchell emphasizes this balance prominently and most effectively. Volume I lays the groundwork with the basics, and Volume II shows how believers can move into adulthood without abandoning the basics. He reminds readers that posture; both physical and spiritual; isn’t something you naturally do. It takes focus, practice, and coaching.

The Christian life is long-term. There’s always something new to discover and more ways to expand. The challenge is to do it with maintaining the balance, that is only possible by developing maturity along with keeping a tight hold on the fundamentals. By maintaining consistent habits, remaining humble, and grounding ourselves in God’s Word, we can continue growing without tripping up.

As faith develops in such a manner, it not only makes us strong but also inspires those around us. In a distorted world, evenhanded growth enables us to walk upright and stride boldly.

All solid structures start with a good foundation. Without it, the most magnificent building will buckle under pressure. The same is applicable to our faith. Our spiritual foundation; our beliefs regarding God, Jesus Christ, and how we respond to Him; dictates how we approach life’s problems. When our core is weak, we stumble. When our core is strong, we stand firm.

It’s easy to get sidetracked by the exterior of life; good habits, productivity, or image; but those don’t last. Just like how our physical posture is built on core strength, our spiritual posture is based on a foundational strength that is grounded in truth.

What a Strong Core Looks Like

A robust spiritual foundation is not about possessing all theological solutions or memorizing infinite facts. It’s about holding on to fundamental truths that govern the way we live: Christ is Lord, His work on the cross saves us, and our response is faith, repentance, and trust. These are not negotiables. They are the foundation of a stable existence.

When storms roll around, as they are bound to do, these truths ground us. Like roots that steady a tree in a strong wind, core beliefs stabilize us. Without them, even the slightest doubts or challenges can topple us.

Habits That Strengthen the Core

How do we build this core? Daily practice. Hearing God’s voice through Scripture reading. Reminding ourselves of Him through prayer, keeping us connected and honest in front of Him. Faith community provides us with encouragement and accountability. These are not quick fixes but habits of a lifetime that gently build our resilience. They become like spiritual exercise over time—quietly forming us into tougher, steadier individuals.

Pastor David Parker Mitchell uses the same imagery in his two-volume series, Christian Posture: Walk Tall, Stand Straight in a Crooked World — Core Doctrines. Volume I establishes the fundamentals, and Volume II reveals how maturity develops from that foundation. His reminder is uncomplicated but powerful: posture, either physical or spiritual, doesn’t occur by chance. It requires intention and purpose.

Perhaps today is the day to verify your foundation. Are you on a firm foundation, or is it unstable? Good news: weakness is not terminal. Just as posture can be restored, so too can faith. By going back to the fundamentals and developing habitual disciplines, we can recreate our spiritual core and stand firm whatever comes our way.
