Summary: We are already God's children, loved deeply by the Father. The world doesn't know us, as it didn't know Him. In the future, we'll fully become like Him, seeing Him as He truly is.
Beloved: See what love the Father has bestowed on us that we may be called the children of God. Yet so we are.
The reason the world does not know us is that it did not know him.
Beloved, we are God’s children now; what we shall be has not yet been revealed. We do know that when it is revealed we shall be like him, for we shall see him as he is.
