“Your record raises troubling questions about whether you appreciate the checks and balances in our Constitution -- the careful efforts of our Founding Fathers to protect us from a government or a president determined to seize too much power over our lives.”

2009, First Inaugural Address (January 2009)
Context: What the cynics fail to understand is that the ground has shifted beneath them — that the stale political arguments that have consumed us for so long no longer apply. The question we ask today is not whether our government is too big or too small, but whether it works — whether it helps families find jobs at a decent wage, care they can afford, a retirement that is dignified. Where the answer is yes, we intend to move forward. Where the answer is no, programs will end.

(Hudson Taylor’s Choice Sayings: A Compilation from His Writings and Addresses. London: China Inland Mission, n.d., 52).
Variant: Let us give up our work, our thoughts, our plans, ourselves, our lives, our loved ones, our influence, our all, right into His hand, and then, when we have given all over to Him, there will be nothing left for us to be troubled about, or to make trouble about.

Statement (26 June 1787) as quoted in Notes of the Secret Debates of the Federal Convention of 1787 http://avalon.law.yale.edu/18th_century/yates.asp by Robert Yates
1780s
Context: The man who is possessed of wealth, who lolls on his sofa or rolls in his carriage, cannot judge the wants or feelings of the day-laborer. The government we mean to erect is intended to last for ages. The landed interest, at present, is prevalent; but in process of time, when we approximate to the states and kingdoms of Europe, — when the number of landholders shall be comparatively small, through the various means of trade and manufactures, will not the landed interest be overbalanced in future elections, and unless wisely provided against, what will become of your government? In England, at this day, if elections were open to all classes of people, the property of landed proprietors would be insecure. An agrarian law would soon take place. If these observations be just, our government ought to secure the permanent interests of the country against innovation. Landholders ought to have a share in the government, to support these invaluable interests, and to balance and check the other. They ought to be so constituted as to protect the minority of the opulent against the majority. The senate, therefore, ought to be this body; and to answer these purposes, they ought to have permanency and stability.
