What does it mean that whoever is born of God “sinneth not”?

When John says that the one who is born of God “sinneth not,” he is not saying believers never commit any sin at all. The letter already speaks about confessing sins. Here he is talking about not living under sin’s rule and not falling into the kind of hard, final rejection of God that leads to spiritual death. The new life God puts inside a believer changes their desires and direction. They may stumble, but they do not give themselves over to sin as their master, and God keeps them from the sin that leads to eternal ruin.

How does the one begotten of God “keepeth himself” and the wicked one toucheth him not?

“Keepeth himself” means the believer, made new by God, is now able to watch and guard their life. This does not mean they protect themselves by their own strength. God is the one who keeps his people, but he also calls them to stay alert, trust him, and resist temptation. The “wicked one” is Satan. He can tempt, trouble, and attack, but he cannot lay hold of the believer in a way that destroys their new life in God or drags them into the final, deadly separation from God. They are out of his control.

What does it mean that “the whole world lieth in wickedness”?

When John says the whole world lies in wickedness, he is describing people who are still outside of God’s family. They live under the pull and power of sin and under the influence of the evil one. Their hearts naturally lean toward what is against God. In contrast, John says, “we are of God.” Believers have been taken out of that dark realm and now belong to God. This sharp contrast is meant to remind Christians not to be shaped by the world’s values, but to remember who they belong to and live as God’s people.

What does this passage teach about the coming of the Son of God and our understanding?

John says, “We know that the Son of God is come, and hath given us an understanding.” This means Jesus really came into the world in human flesh and has given believers inner light to know God. It is not just head knowledge, but a God-given ability to see that the God Jesus shows us is the true God. Through Jesus, people come to know God as he really is, not as idols or human ideas describe him. This knowledge is part of eternal life, because eternal life is knowing the true God through his Son.

Why does John say, “This is the true God, and eternal life”?

The wording here has been read in more than one way. Many understand John to be saying that the Son of God, Jesus Christ, is himself the true God and eternal life. Others take him to be pointing back to the Father as the true God, revealed through the Son. In either case, John is clear that through Jesus we know the only real God, and that in knowing him we have eternal life. Eternal life is not just living forever, but sharing in the life that comes from the true God through his Son.

What does it mean that we are “in him that is true, even in his Son Jesus Christ”?

To be “in him that is true” means believers share a living, close connection with the true God and with his Son, Jesus Christ. They are not just learning about God from a distance. They are brought into his favour, rescued by his grace, and joined to Christ like branches to a vine. This union shows itself in faith, love, and obedience. Being “in” the Father and the Son is a great comfort, because it means the believer’s life is held inside the one who is the true God and eternal life.

Why does John end by saying, “Little children, keep yourselves from idols”?

John finishes with a simple but strong warning because he has just spoken about the true God. If God has shown himself through Jesus, then anything that pretends to take God’s place is an idol. In his time, this included the false gods and images of the surrounding culture, and also any teaching that twisted who God and Jesus really are. An idol can also be any created thing that takes God’s place in the heart. To “keep yourselves from idols” means to refuse any rival to God’s place, whether in worship, belief, or deepest love.

How does this passage apply to believers living in the world today?

This passage reminds believers today that they belong to God in a world still lying in wickedness. They should not be surprised by evil, but also should not be ruled by it. Knowing that the wicked one cannot finally grasp them gives courage to resist temptation. Knowing that the Son of God has come and given understanding keeps them focused on the real God, not on passing ideas or pleasures. The call to keep away from idols still fits, warning believers not to let anything, even good things, take God’s first place in their hearts.

Why is this passage sometimes hard to understand about sin and being born of God?

Some struggle with this passage because it sounds like believers never sin, which does not match daily experience. The key is to see that John speaks about sin as a settled way of life and about a kind of sin that leads to final death. Those born of God no longer live under sin’s rule and are kept from that deadly turning away from God. They still need to confess and fight sin, but their new birth changes their direction. This tension can feel hard, but it shows both the seriousness of sin and the strength of God’s keeping grace.

1John.5.18

1 John 5:18

KJV

We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.

The True God

We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.

And we know that we are of God, and the whole world lieth in wickedness.

And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.

Little children, keep yourselves from idols. Amen.
