First John 5:2 teaches that we can tell we truly love God’s children when our love for God shows up in obedience to his commands. The verse is written by the apostle John, who is traditionally named as the author of this letter, to a community of Christians he calls his “little children.” He writes to believers who need a clear test for whether their love is real.
By this we know that we love the children of God, when we love God and keep his commandments.

What 1 John 5:2 Means
The verse begins with “By this we know,” which tells you John is giving a sign, a way of recognizing something that is otherwise hard to see. The thing being recognized is that we love the children of God. In John’s usage, the children of God are fellow believers, those who have been born into God’s family through faith in Jesus.
The verse then names the evidence: “when we love God and keep his commandments.” Love for other believers is tied directly to love for God, and love for God is shown by obeying what he has asked. John is not describing a feeling as the proof. He is pointing to a pattern of life that others and we ourselves can observe.
What the verse does not do is promise that loving God will always feel easy or that obedience will bring instant results. It also does not say we become God’s children by keeping commandments. The surrounding verses make clear that new birth comes first, and love and obedience follow from it.
The Context of 1 John 5:2
First John is a letter that addresses believers who were facing false teaching and confusion about who Jesus is and how Christians should live. John presses hard on two points that belong together: belief that Jesus is the Christ, and love that is visible in action. The verses just before this one say that whoever believes Jesus is the Christ has been born of God and that loving the Father includes loving the child born of him.
The verses that follow clarify what John means by keeping commandments. He says, “His commandments are not grievous,” meaning they are not a crushing burden. He then explains that faith is what overcomes the world. Read in this setting, verse 2 is not a call to anxious perfectionism. It is part of a letter that ties love, faith, and obedience together as the healthy life of someone who belongs to God.

A Short Prayer From 1 John 5:2
Father, you have made us part of your family through your Son, Jesus. Help us to love the brothers and sisters you have given us, not only in words but in patient, truthful action. Show us where our love has grown cold, and draw us back to you. Give us a willing heart to keep your commandments, trusting that your ways are good and that they are not too heavy for us. Let our love for you and for your people be the honest proof that we belong to you. Amen.
