Dear friends, we are now God's children, but what we are to be in the future has not yet been fully revealed. We know that if Christ reappears we shall be like Him, because we shall see Him as He is.
»Father, those whom Thou hast given me – I desire that where I am they also may be with me, that they may see the glory –my glory– my gift from Thee, which Thou hast given me because Thou didst love me before the creation of the world.
For those whom He has known beforehand He has also pre-destined to bear the likeness of His Son, that He might be the Eldest in a vast family of brothers;
For the present we see things as if in a mirror, and are puzzled; but then we shall see them face to face. For the present the knowledge I gain is imperfect; but then I shall know fully, even as I am fully known.

so the Christ also, having been once offered in sacrifice in order that He might bear the sins of many, will appear a second time, separated from sin, to those who are eagerly expecting Him, to make their salvation complete.
It is by means of these that He has granted us His precious and wondrous promises, in order that through them you may, one and all, become sharers in the very nature of God, having completely escaped the corruption which exists in the world through earthly cravings.
And now, dear children, continue in union with Him; so that, if He re-appears, we may have perfect confidence, and may not shrink away in shame from His presence at His Coming.
My dearly-loved friends, it is no new command that I am now giving you, but an old command which you have had from the very beginning. By the old command I mean the teaching which you have already received.
See what marvellous love the Father has bestowed upon us –that we should be called God's children: and that is what we are. For this reason the world does not recognize us– because it has not known Him.
By this we can distinguish God's children and the Devil's children: no one who fails to act righteously is a child of God, nor he who does not love his brother man.
