1 John 3:8 – “The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work.”
Extended Explanation
This verse is very direct and might sound harsh at first, but it’s meant to make something very clear: Sin is not neutral.
John is saying that when a person lives in sin, practices sin, and follows a life marked by sin, they are showing that they belong to the devil, not to God.
John is not talking about people who stumble and sin sometimes.
He’s talking about people who practice sin as a lifestyle, who have no desire to turn away from it.
The reason for this, John says, is because sin has its source in the devil.
The devil has been sinning and rebelling against God from the very start.
When people live in ongoing, unrepentant sin, they are following in the devil’s footsteps, not God’s.
But John doesn’t leave us there. He reminds us why Jesus came.
The Son of God appeared to destroy the devil’s work.
Sin, rebellion, deception, death—all of these things are the devil’s work, and Jesus came to break their power and set people free.
Historical Context
In John’s time, false teachers were confusing believers, making them think that sin wasn’t serious or that it didn’t matter how they lived.
John is cutting through the lies.
He’s reminding the church that sin is not just a bad habit—it’s part of a spiritual battle.
There are two sides: God’s side and the devil’s side.
John wants believers to know that how they live shows which side they belong to.
Theological Implications
This verse reveals that sin is rooted in rebellion against God, and that rebellion is not random—it has a source.
John is pointing to the spiritual reality behind sin:
There is an enemy, the devil, who has been working against God and leading people into sin from the very beginning.
The verse also shows the purpose of Jesus’ coming:
He appeared to destroy the devil’s work.
This is not just about forgiving sins; it’s about breaking the power of sin, evil, and death.
Through Jesus’ life, death, and resurrection, the devil’s plans have been defeated.
Literary Analysis
John uses strong and simple language.
“The one who does what is sinful is of the devil.” There’s no middle ground in his words.
John often uses black-and-white language in this letter to make things clear.
He also uses “from the beginning” to remind readers that sin has always been tied to the devil’s rebellion.
The second half of the verse is full of hope:
“The reason the Son of God appeared was to destroy the devil’s work.”
The word destroy is powerful. It means to undo, break, and tear down everything the devil has built.
