1 John 2:3 Meaning: Can Obedience Prove We Know God?
This is how we know that we know him: if we keep his commandments.
And hereby we do know that we know him, if we keep his commandments.
And hereby we know that we know him, if we keep his commandments.
and in this we know that we have known him, if his commands we may keep;
And hereby we know that we know him, if we keep his commandments.
Meaning in one sentence
1 John 2:3 explains that keeping God's commandments gives us assurance that we truly know Him, not as works but as the fruit of genuine faith.
Context
John writes to believers who were being challenged by false teachers. These teachers claimed a special, secret knowledge of God, yet their lives showed no real change. They said they knew God, but they ignored His commands. John wrote this letter to set the record straight: true knowledge of God is not a mystical feeling or an elite insight. It changes the way you live. In the verses just before this, John talked about walking in the light and confessing sin. Now he gives the practical test. If you say you know God, your obedience to His commandments proves it. This was not a new idea. Jesus Himself said the same thing: love Me, keep My commands. John is calling believers back to the kind of faith that shows itself in action.
Key Words
Two different Greek words for know stand side by side in this verse. The first, ginōskomen, means we are coming to know, an ongoing, daily knowing by experience. The second, egnōkamen, means we have come to know, a settled, personal knowledge once received and still held. John uses both to say that assurance is not a single moment you look back on, but a present experience that grows as you walk with Christ. The word behind keep is tērōmen. It does not mean casual observance. It means to guard, to watch over, to protect something precious as you would a treasure. We keep His commandments the way a friend keeps a promise. This is not checking off a list. It is holding on to what matters to God because you know Him and love what He loves.
How Christians Read This Verse
Across traditions, Christians have seen this verse as a safeguard against empty claims of faith. Reformation teachers like Calvin said that the knowledge of God is never cold or idle, it always produces obedience. Matthew Henry called it the trial of our light. In the Wesleyan tradition, Wesley read it as the proof of saving knowledge, especially faith and love. Catholic and Orthodox readings would add that this keeping of the commandments is the work of grace through love. All agree on the central point: the verse is not about earning God’s favor, but about knowing that you truly belong to Him. Where the knowledge is real, the life follows.
A common misunderstanding
Some read this verse and think John is teaching salvation by good deeds. In fact, John is not telling you how to be saved. He is telling you how to be sure you are saved. The false teachers in his day claimed a special knowledge of God while living in disobedience. John says that if your life shows no sign of following Christ, you have no reason to be certain you know Him at all. Obedience is not the root of salvation; it is the fruit that proves the root is alive.
Living This Out
This week, when doubt creeps in and you wonder if you really know God, stop and look at the pattern of your life. Not at one failure or one good day. Look at the direction you are walking. Are you guarding His commandments as a treasure? That does not mean perfection. It means you care about what He cares about. If you find one of His commands you have been ignoring, forgiveness, honest speech, love for a difficult person, start there. Keep it the way you would hold a gift. Not to earn anything, but because knowing Him has already changed what you value.
Main takeaway: Our obedience to God’s commands is the evidence that we truly know Him, not the grounds for knowing Him in the first place.
For Families
For ages 5, 8
Saying you love Jesus means you do what He says. When you obey your parents, that shows you love them. When you obey God, it shows you love Him. That’s how you know you really know Him.
For ages 9, 12
Have you ever told someone you are friends with them but then ignored them all day? That wouldn’t feel like real friendship. John says the same thing about knowing God. You cannot claim to know Him and just do whatever you want. The way you treat people, the choices you make, the things you say, those show whether your friendship with God is real. You don’t have to be perfect. But your life should point in His direction.
Questions People Ask
What does 1 John 2:3 mean?
John is telling believers how to have assurance that their faith is real. He says the evidence is keeping God's commandments. This does not mean you are saved by obedience. It means that if you truly know God, your life will naturally begin to follow what He says. The verse is a test of genuine faith, not a demand to earn salvation.
Does 1 John 2:3 teach salvation by works?
No. The verse is not about how to become a Christian, but about how to know you are one. John is writing to people who already believe. He is giving them a way to check their own hearts. If someone claims to know God but lives in disobedience, they are deceiving themselves. Obedience does not save you; it proves you are saved.
What commandments is John talking about in 1 John 2:3?
John likely has in mind the commandments of Jesus, especially faith in Christ and love for one another. In the surrounding verses, he talks about loving your brother and walking as Jesus walked. The specific commandments are not a legal code, but the teachings of Christ summed up in love for God and neighbor.
Why does John use two different words for 'know' in 1 John 2:3?
The first word (ginōskō) means coming to know by experience, day by day. The second word (egnōka) means having come to know, a settled knowledge. John is saying that your daily experience of walking with God confirms the once-for-all knowledge you received when you first believed. Both are needed for assurance.
How can I be sure I really know God?
John points to obedience as the evidence. Not a perfect life, but a life that is moving toward God's will. Ask yourself: Do I care about what God commands? When I fail, do I come back to Him? Am I learning to love others more? If yes, that is the fruit of knowing Him. The Holy Spirit in you produces that desire to obey. It is a quiet but real proof.
