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. Beloved, we are God’s children now; what we will be has not yet been revealed. What we do know is this: when he is revealed, we will be like him, for we will see him as he is. And all who have this hope in him purify themselves, just as he is pure.
Wherefore, my beloved brethren, pray unto the Father with all the energy of heart, that ye may be filled with this love, which he hath bestowed upon all who are true followers of his Son, Jesus Christ; that ye may become the sons of God; that when he shall appear we shall be like him, for we shall see him as he is; that we may have this hope; that we may be purified even as he is pure. Amen.
Origen. . . from Him there began the union of the divine with the human nature. This was so that the human – by communion with the divine – might rise to be divine. This not only happened in Jesus, but also in all those who not only believe, but enter upon the life that Jesus taught.
Be perfect, therefore, as your heavenly Father is perfect.
