"The king's heart is in the hand of the LORD, as the rivers of water: he turneth it whithersoever he will." (Proverbs 21:1)
A river may seem to meander aimlessly, but it eventually reaches its goal. The twists and turns along the way are constrained by a variety of hydraulic and geologic facts that determine its local speed and direction, but somehow it "just keeps rolling along" toward the sea.
So it is with a king—or with a president, or any leader of a state or nation. He may have a goal in mind (honorable or otherwise) for the nation he governs, but there are numerous people and circumstances along the way that will either impede or help his progress toward that goal. In fact, we ourselves—the Christian citizens of this nation—are an integral component of those circumstances.
But the president's heart is in the hands of God. In fact, "the powers that be are ordained of God" (Romans 13:1). Whether the ruler comes into power by election or inheritance or coup d'etat or some other way (depending upon the nation and type of government), God is in control and will accomplish His ultimate goal.
That is why it is vital that we frequently make "supplications, prayers, intercessions, and giving of thanks . . . for all men," especially for "kings, and for all that are in authority" so that we will all be able to "lead a quiet and peaceable life in all godliness and honesty" (1 Timothy 2:1-2).
Our American nation has had many great men as our presidents over the years, and many of our ancestors were indeed men and women of prayer. We do have a great heritage in our nation of both leaders and followers who believed in the Creator God of the Bible and who prayed diligently for their country and the great decisions of its history. We must—must—do the same today! HMM
