Can we not hear John asking, “Where is your treasure invested?”

It is the highest activity of the human soul, and therefore it is at the same time the ultimate test of a man’s true spiritual condition.  There is nothing that tells the truth about us as Christian people so much as our prayer life. . . . Ultimately, therefore, a man discovers the real condition of his spiritual life when he examines himself in private, when he is alone with God. . . . And have we not all known what it is to find that, somehow, we have less to say to God when we are alone than when we are in the presence of others?  It should not be so; but it often is.  So that it is when we have left the realm of activities and outward dealings with other people, and are alone with God, that we really know where we stand in a spiritual sense (Martin Lloyd-Jones, Studies in the Sermon on the Mount)

“No foreign power or combination of foreign powers could by force take a drink from the Ohio or make a track on the Blue Ridge in a trial of a thousand years.  At what point then is the approach of danger to be expected?  I answer, if it ever reach us it must spring up from among us, it cannot come from abroad.  If destruction be our lot, we must ourselves be its author and finisher.  As a nation of freemen we must live through all time or die of suicide.” Abraham Lincoln

This does not mean that the unsaved person never does anything good, or that the believer never does anything bad. It means that the bent of their lives is different.  One lives for the flesh, the other lives for the Spirit.  (Wiersbe, W. W. (1996, c1989). The Bible exposition commentary.  "An exposition of the New Testament")

Rom 8:8 ⁽¹⁰⁾ So then they that are in the flesh cannot please God.

(10) The conclusion. Therefore they that walk after the flesh cannot please God: by which it follows that they are not grafted into Christ. (Geneva Bible Translation Notes)

The classroom must and will become an arena of conflict between the old and the new—the rotting corpse of Christianity, together with all its adjacent evils and misery, and the new faith of humanism, resplendent in its promise of a world in which the never-realized Christian ideal of ‘love thy neighbor’ will be finally achieved.”  John J. Dunphy, “A Religion for a New Age,” The Humanist (January/February 1983), 26

To be carnally minded: To be under the dominion of the fleshly impulses of the body. (The People's New Testament)

Whatever the flesh savors, that brings about death: and whatever the Spirit savors, that is conducive to joy and everlasting life. (Geneva Bible Translation Notes)

Complaining: goggusmos {gong-goos-mos’} The early instances yield the sense “to be dissatisfied,” “to grumble because of disappointed hopes.” A murmur, murmuring, muttering; a secret debate; a secret displeasure not openly avowed.

The man is as the mind is….Which way do our thoughts move with most pleasure?  Which way go our plans and contrivances?  Are we most wise for the world, or for our souls? (Matthew Henry)

"This transformation, it must be conceded, rather than representing the greatest thing impotent man can do for God, represents the greatest thing the infinite God can do for man; for there is nothing to be conceived of beyond the estate to which this salvation brings one, namely, ‘like Christ’ and ‘conformed to the image of his Son.’” Dr. Lewis Sperry Chafer, D.D., Litt.D., Th.D., Salvation

Thus satisfaction was made to Divine justice, and the way of salvation opened for the sinner.  By the Spirit the law of love is written upon the heart, and though the righteousness of the law is not fulfilled by us, yet, blessed be God, it is fulfilled in us; there is that in all true believers, which answers the intention of the law. (Matthew Henry)

He does not use an argument here, but expounds the mystery of sanctification, which is imputed to us: because, he says, the power of the law was not such (and that by reason of the corruption of our nature) that it could make man pure and perfect, and because it rather kindled the flame of sin than put it out and extinguish it, therefore God clothed his Son with flesh just like our sinful flesh, in which he utterly abolished our corruption, that being accounted thoroughly pure and without fault in him, apprehended and laid hold of by faith, we might be found to fully have the singular perfection which the law requires, and therefore that there might be no condemnation in us.
