Truth Matters: Why Knowing God Goes Deeper Than Knowing About Him
There is a difference between knowing words and knowing the one behind them. It is a distinction that cuts to the heart of what it means to follow God, and it is one that many of us quietly struggle with, often without realizing it.
In 1 John chapter 4, the apostle John delivers a pointed challenge to believers: do not accept every spirit at face value, but test them. Why? Because false teachers are real, deception is active, and the stakes could not be higher. But before we can understand what it means to test the spirits, we need to grapple with something more foundational. We need to understand why truth matters, and why it cannot be separated from love.
The Pharisees Knew the Words and Missed the Point
Few examples in Scripture illustrate this tension more clearly than the Pharisees. They were meticulous. They followed the law. They memorized the scriptures. By every outward measure, they appeared to be the most devoted people in the room. And yet Jesus repeatedly confronted them because something was missing at the center of it all.
In Matthew 23, Jesus acknowledged that the Pharisees held positions of authority and that the people should heed their teaching. But he also exposed a troubling reality: these leaders were performing their devotion for an audience. They wanted to be seen. They added layers of tradition onto the law, burdens that were never meant to be carried, and in doing so they drifted further and further from the heart behind the commands.
One of the most telling examples involves ceremonial hand-washing. What was originally a priestly act of preparation for temple service had been expanded into a rigid social requirement for everyone, applied before meals, between courses, and after eating. In Mark chapter 7, Jesus confronts the Pharisees directly, pointing out that they had found a way to set aside the commands of God in order to honor their own traditions. They were nullifying the word of God with their customs.
The problem was not that they were doing things. The problem was that they were doing things without understanding why. They knew the truth, but they had lost the love behind it. And without that love, the truth became a performance rather than a transformation.
Doing the Right Things for the Wrong Reasons
This is not just an ancient problem. It shows up in churches today whenever people come looking for a list of steps to follow rather than a God to know. There is nothing wrong with practical teaching. But if all we want is a formula for being a better parent or a more productive employee, we are missing the deeper invitation. The goal is not better behavior. The goal is a changed heart, and a changed heart produces better behavior as a natural result.
When we truly begin to know God, not just know about him, our hearts start to align with his. We begin to care about what he cares about. We love people more genuinely. We extend grace more freely. We live differently in our homes and workplaces, not because we are following a checklist, but because something has shifted on the inside. That is what spiritual maturity looks like.
Paul captures this beautifully in Ephesians 4, describing a church that speaks the truth in love and grows together into the fullness of Christ. The goal is not to remain spiritual infants, tossed around by every new wind of teaching. The goal is to grow up, to become grounded in both truth and love simultaneously.
The Truth That Must Be Believed
So what is the truth that John is protecting? It is this: Jesus Christ came in the flesh. He was fully God and fully man. Any spirit, any teacher, any message that denies this is not from God. It is that straightforward.
This was not a minor theological debate in John's day. There were teachers circulating through the early church who questioned whether God could truly take on human form. John draws a clear line. The test of a true spirit is its confession that Jesus is the Christ, the anointed one, God incarnate.
Jesus himself made no effort to hide this claim. In John 10, when the religious leaders demanded that he speak plainly about whether he was the Messiah, he told them that he and the Father are one. His enemies understood exactly what he was saying. They called it blasphemy. They wanted to stone him for it. But the disciples, empowered by the Holy Spirit, understood it as the fulfillment of everything the Old Testament had been pointing toward.
This is why the Old Testament matters as much as the New. The Gospels do not stand alone. They are the culmination of centuries of prophecy, promise, and preparation. When Matthew quotes Isaiah 7:14 to describe the virgin birth, or when Peter stands before Cornelius and traces the story of Jesus back through the prophets, they are drawing a straight line from God's ancient promises to their present reality. The whole Bible is one coherent story, and Jesus is at the center of it.
The Spirit of Truth Lives in You
Here is where the message becomes deeply personal. John reminds believers that the one who is in them is greater than the one who is in the world. The Holy Spirit, the spirit of truth, is not a distant resource. He is present, active, and teaching.
Jesus promised in John 16:13 that when the spirit of truth comes, he will guide his people into all truth. This is not passive. It requires surrender, attentiveness, and a willingness to test what we hear against the apostles' teaching and the testimony of Scripture.
When something does not align with love, it is not from God. When something does not align with the truth of who Jesus is, it is not from God. The Holy Spirit within us bears witness to these things, and we must learn to listen.
The invitation, then, is not merely to believe the right things. It is to know the one who is true, to worship in spirit and in truth as Jesus described to the woman at the well, and to let that knowledge work its way from the inside out. That is where life is found.
