The highest privilege of the Christian Life is our adoption as children into God’s eternal family through God’s natural Son, Jesus Christ. (Discipleship Essentials, pg. 112)
See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him. Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is.
1 John 3:1-2
