loving each other means what?

1 John 3:11 This is the message you have heard from the beginning:

     We should love one another.

12 We must not be like Cain, who belonged to the evil one and killed his brother.

And why did he kill him?

     Because Cain had been doing what was evil,

     and his brother had been doing what was righteous.

13 So don't be surprised, dear brothers and sisters, if the world hates you.


14 If we love our Christian brothers and sisters, it proves that we have passed from death to life.

     But a person who has no love is still dead.

15 Anyone who hates another brother or sister is really a murderer at heart.

And you know that murderers don't have eternal life within them.


16 We know what real love is because Jesus gave up his life for us.

      So we also ought to give up our lives for our brothers and sisters.

17 If someone has enough money to live well and sees a brother or sister in need but shows no compassion - how can God's love be in that person?


18 Dear children, let's not merely say that we love each other;

      let us show the truth by our actions.

19 Our actions will show that we belong to the truth,

      so we will be confident when we stand before God.
