while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal.

For,
“All flesh is like grass,
And all its glory like the flower of grass.
The grass withers,
And the flower falls off,

A voice says, “Call out.”
Then he answered, “What shall I call out?”
All flesh is grass, and all its loveliness is like the flower of the field.
The grass withers, the flower fades,
When the breath of the Lord blows upon it;
Surely the people are grass.

For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished.

Heaven and earth will pass away, but My words will not pass away.

Heaven and earth will pass away, but My words will not pass away.

Heaven and earth will pass away, but My words will not pass away.

and those who use the world, as though they did not make full use of it; for the form of this world is passing away.

And,
“You, Lord, in the beginning laid the foundation of the earth,
And the heavens are the works of Your hands;
They will perish, but You remain;
And they all will become old like a garment,
And like a mantle You will roll them up;
Like a garment they will also be changed.
But You are the same,
And Your years will not come to an end.”

And His voice shook the earth then, but now He has promised, saying, “Yet once more I will shake not only the earth, but also the heaven.” This expression, “Yet once more,” denotes the removing of those things which can be shaken, as of created things, so that those things which cannot be shaken may remain.
