If we love and obey God, we know that we will love his children.
So I command you to love each other.
When we obey God, we are sure that we know him.
We truly love God only when we obey him as we should, and then we know that we belong to him.
Our love for each other proves that we have gone from death to life. But if you don't love each other, you are still under the power of death.
The commandment that God has given us is: “Love God and love each other!”
