See what love the Father has given us, that we should be called children of God; and that is what we are. The reason the world does not know us is that it did not know him. (1 John 3: 1)
I’ve always liked the conclusion of the first sentence of this verse: “and that is what we are.” God loves us, we are called children of God, because that is what we are, all because of God’s love.
It’s not surprising that people don’t understand us at times, because people ususally get God wrong. In fact, the closer we are to God, the more this misunderstanding is likely. Why do you care about the things of the spirit? Why love one another when you should just look out for yourself? Why give your money away? Why risk the label of “intolerant” just to maintain some foolish morality that we don’t believe? Why spending time praying to an invisible being?
But as God’s children we do understand. We care about the things of the spirit, because God has moved us, and we want to know God better. We love one another because God is a being who loves, God so identifies with love that God allows the truth of the identity “God is love.” We give our money away because we follow God’s profligate example. We try to be consistent morally (and often fail) because our focus is God-ward. We spending time praying because, well, at least just because it’s polite to ask, and we have seen how God has acted on our behalf in the past.
We are called the children of God, and so we are.
