HOW TO IDENTIFY CHILDREN OF GOD AND THE DEVIL?

So now we can tell who are children of God and who are children of the devil. Anyone who does not live righteously and does not love other believers does not belong to God. (1 John 3:10 NLT)

That our love does not stay in words.

Dear children, let’s not merely say that we love each other; let us show the truth by our actions. (1 John 3:18 NLT)

How to receive everything we ask for?

And we will receive from him whatever we ask because we obey him and do the things that please him. (1 John 3:22 NLT)

No one has seen God, but it can be seen when God lives in someone.

No one has ever seen God. But if we love each other, God lives in us, and his love is brought to full expression in us. (1 John 4:12 NLT)

Where does God live?

All who declare that Jesus is the Son of God have God living in them, and they live in God. (1 John 4:15 NLT)
Think about it:

What can you do for someone to demonstrate your love toward them?
What would you like to receive from God? What changes do you need to make to assure that you receive it?
Does God live in you and you in Him?
