1 John 3:1
See how great a love the Father has bestowed on us, that we would be called children of God; and such we are. For this reason the world does not know us, because it did not know Him.
God’s love for us is so incredibly great that He has chosen to adopt not just one, or two, or a dozen, but every single one of us to be called and identified had His sons. This is what I am. This makes us uniquely different from all other people who have not accepted this precious gift, and they cannot understand who and what we are because they do not know God like we do, but they can if we reveal Him to them through our lives.
What can be better than God calling you His very own son!
