Hebrews 5:14
Now then do you know where these words are? For myself I do not think you do, except a few. And yet every week these things are read to you twice or even three times: and the reader when he goes up [to the desk] first says whose the book is, [the book] of such a prophet, and then says what he says, so that it shall be more intelligible to you and you may not only know the contents of the Book, but also the reason of the writings, and who spoke these things. But all in vain; all to no purpose.
For your zeal is spent on things of this life, and of things spiritual no account is made. Therefore not even those matters turn out according to your wishes, but there also are many difficulties. For Christ says, “Seek the Kingdom of God, and all these things shall be added unto you.” These things He said, shall also be given in the way of addition: but we have inverted the order and seek the earth and the good things which are in the earth, as if those other [heavenly] things were to be given us in addition.
Therefore we have neither the one nor the other. Let us then at last wake up and become coveters of the things which shall be hereafter; for so these also will follow. For it is not possible that he who seeks the things that relate to God, should not also attain human [blessings]. It is the declaration of the Truth itself which says this. Let us not then act otherwise, but let us hold fast to the counsel of Christ, lest we fail of all. But God is able to give you compunction and to make you better, in Christ Jesus our Lord, with whom to the Father together with the Holy Ghost be glory, power, honor, now and for ever and world without end. Amen.
