This was not, however, because He could not redeem us in another way, but so that His surpassing love, manifested hereby, might be a teacher unto us.
And by the death of His Only-begotten Son He made us near to Himself.
Yea, if He had had anything more precious, He would have given it to us, so that by it our race might be His own.
Because of His great love for us it was not His pleasure to do violence to our freedom, although He is able to do so, but He chose that we should draw near to Him by the love of our understanding.
For the sake of His love for us and obedience to His Father, Christ joyfully took upon Himself insult and sorrow…
In like manner, when the saints become perfect, they all attain to this perfection, and by the superabundant outpouring of their love and compassion upon all men they resemble God.

But now, when He poured out His grace upon the world through His own coming, He has descended not in an earthquake, not in a fire, not in a terrible and mighty sound, but “as the rain upon a fleece, and rain-drops that fall upon the earth” softly, and He was seen conversing with us after another fashion.
This came to pass when, as though in a treasury, He concealed His majesty with the veil of His flesh, and among us spoke with us in that body which His own bidding wrought for Him out of the womb of the Virgin.
