Tonight, I was talking with a friend, and we mentioned the things believers do that they know they shouldn’t be doing. Not people who are new to the faith or confused, but people who are deep in Scripture, experienced, and knowledgeable. People who would say they love God. People who, if I’m being honest, I’d say should “know better.”
For most of these situations, the issue isn’t a lack of knowledge. It isn’t that God hasn’t spoken. It’s that people have learned how to live around His voice.
Culture plays a huge role in this. There are behaviors Scripture addresses plainly, yet culture normalizes them. Traditions soften them. Even Christian spaces excuse them. Over time, people start believing that if something is common enough, accepted enough, or emotionally comfortable enough, then it must be fine. But for a true believer, that explanation only works on the surface.
Because if you belong to Christ, you have heard the truth at some point.
I know this because I’ve lived it. I’ve been in seasons where I heard the warning, felt the check in my spirit, and still chose comfort, still chose tradition. I didn’t rebel chaotically. I delayed. I reasoned. I justified. I told myself I would deal with it later, or I’d say, “that’s not true,” without ever really studying it myself. And every time I did that, it became easier to do it again.
After that conversation, I was led back into the account of the plagues in Exodus. What struck me wasn’t just the judgment itself, but the pattern. As I studied the plagues again, I realized that what we had mentioned in a modern, personal way was already clearly laid out in Scripture.
Let’s look there.
We are in Exodus. We are watching God confront Pharaoh. And what I am comparing our lives to is not a vague idea, but a real, recorded pattern of how hearts harden over time when truth is repeatedly resisted.
Pharaoh did not wake up one morning with a hardened heart. It happened gradually. He saw the signs. He heard the warnings. He experienced loss. And still, he refused to surrender. Each refusal made the next one easier.
That realization hit me hard.
Hardening is not the absence of God’s voice. It is the decision to stop responding to it.
God warned Pharaoh again and again. The plagues were not subtle. They were visible, disruptive, and undeniable. Pharaoh was never confused about what God wanted. He simply chose resistance. Over time, resistance stopped feeling dangerous and started feeling normal. What once stirred fear became manageable. Conviction dulled. Pride settled in.
And that same pattern shows up in believers today.
There are things people know they should not be doing. Not because a pastor said so, but because God already said so. The nudge came. The warning came. The discomfort came. It had to, at some point, in some way. But instead of obedience, there was delay. Instead of repentance, there was justification. Culture became cover. Tradition became permission. Grace became misunderstood as approval.
That choice doesn’t leave a person neutral.
Every ignored warning trains the heart to resist. Every delayed act of obedience weakens spiritual sensitivity. Conviction doesn’t fade because God stops speaking. It fades because the heart learns how to override Him.
At some point, I had to face this in my own life. There came a moment where I realized I couldn’t keep managing conviction. I had to come under it. I had to decide that the fear of the Lord mattered more than comfort, more than tradition, more than what felt normal or acceptable.
Scripture says the fear of the Lord is the beginning of wisdom. That fear isn’t terror. It’s reverence. It’s the moment you realize God’s voice isn’t a suggestion. His warnings aren’t optional. His truth isn’t negotiable.
Many believers don’t need more teaching. They already know. What they need is surrender.
Pharaoh’s story is a warning for anyone who thinks knowledge alone is enough. Exposure to truth does not guarantee obedience. In fact, the more truth a person hears without responding, the harder repentance becomes. Hardened hearts are not formed in ignorance. They are formed by repeatedly choosing comfort over obedience.
The plagues make this clear. Rejecting truth doesn’t pause spiritual movement. It moves it in the wrong direction. Resistance compounds. Conviction weakens. Pride strengthens. What once felt wrong eventually feels justified.
But the warning also carries hope.
Hardening can stop the moment surrender begins. The fear of the Lord can still break through pride. Obedience can restore sensitivity. But it requires honesty. It requires humility. It requires choosing God over what feels safe, familiar, or culturally accepted.
Pharaoh refused until it cost him everything.
Scripture gives us his story so we don’t have to learn the same way.
