The Father has loved us so much that we are called children of God. And we really are his children. The reason the people in the world do not know us is that they have not known him.
“I, the Lord, said, ‘How happy I would be to treat you as my own children and give you a pleasant land, a land more beautiful than that of any other nation.’ I thought you would call me ‘My Father’ and not turn away from me.
“But the number of the Israelites will become like the grains of sand of the sea, which no one can measure or count. They were called, ‘You are not my people,’ but later they will be called ‘children of the living God.’
So we can see who God’s children are and who the devil’s children are: Those who do not do what is right are not God’s children, and those who do not love their brothers and sisters are not God’s children.
Dear friends, now we are children of God, and we have not yet been shown what we will be in the future. But we know that when Christ comes again, we will be like him, because we will see him as he really is.
