In verse one of chapter three, Paul tells us to “set your hearts on things above”, which ultimately means to choose to make that which we value and desire above all else to be the things of heaven, the things of God. Here in verse 2, Paul then tells us also to “set your minds on things above, not on earthly things”. What Paul does here is make us aware of one of the primary results of “setting our hearts on things above”. We will recall that this is an admonition to make these “things above” that which we value and desire above all else. When we choose to do so, our minds will naturally be set upon things above as well. The Greek term translated as “set your minds” is phroneite, here as a present imperative verb. This is a compound word, comprised of the words phren and noeo. Phren is a word referring to the diaphragm and noeo is a word referring to our thinking. The question then arises as to why Paul would use a word referring to the diaphragm here. The diaphragm is the body part which essentially controls our breathing, controls the flow of air we intake. The basic idea here is one of control, we are to control our thinking, to think about what we think about. We are in control of (and accountable for) what we set our minds on, and we tend to think about (set our minds on) that which is most valuable to us, that which desire above all else. What Paul then tells us here is to set our minds on “things above, not on earthly things”. His primary emphasis is upon our “thinking”, upon the means by which we ultimately define reality, upon the source of our “worldview”. We ultimately get our worldview from others, and two “sources” are presented here, referred to as heaven and earth. These of course refer to a worldview which is derived from the Word of God or one which is derived from any other source. One whose heart is set upon things above will live out of a biblical worldview, while one whose heart is set upon the things of earth will live out of an earthly worldview. The worldview which we adopt will ultimately determine how we think and what we choose to think about, so we must take great care assure that we “set our minds on things above”, that we make the deliberate choice to live out of a Biblical worldview, and reject the temptations of the enemy to accept and live out of any other worldview.
