“Whoever looks at a woman 
		to lust for her has already committed adultery” 
		
		(Matthew 5:28). 
		These are radical words and even kingdom citizens must struggle not to 
		resist. Their severe probing of the heart brings pain as the Son of God 
		touches the raw nerves of our moral diseases. Jesus, having dealt with 
		the problem of hate and malice, now addresses the problem of lust. The 
		Pharisees had certainly treated the issue of adultery, but only 
		superficially. Their concern was to avoid a capital offense 
		
		(Leviticus 20:10; Deuteronomy 22:22). 
		One can almost hear the 
		way they said, “You shall not commit adultery” 
		
		(Exodus 20:14). 
		Jesus, in contrast, tracks the sin of adultery to its lair 
		
		(Matthew 15:19). 
		As the hatred of the heart is murder, so is the unbridled lust of the 
		heart adultery.
		
		This principle was not an 
		obscure part of the Mosaic covenant. The tenth commandment pointedly 
		said, “You shall not covet your neighbor’s wife” 
		
		(Exodus 20:17). 
		Paul, while still a stranger to the gospel, and a Pharisee, had been 
		severely penetrated by this command 
		
		(Romans 7:7). Even 
		Job, a man who apparently lived before the law, understood this ethical 
		truth. “I have made a covenant with my eyes,” he said, “Why then should 
		I look upon a young woman?” 
		(Job 
		31:1).
		
		Though some extended 
		application might be made from this passage to the raw and unprincipled 
		carnal desire which some single person might harbor for someone 
		similarly unattached, Jesus’ use of the word “adultery” makes clear that 
		His present concern is with that illicit desire which violates the very 
		spirit of the marriage covenant 
		(2 
		Corinthians 11:2-3). 
		The Lord’s concern in this whole section is with our duty to love 
		others. No married person can do justice to his mate while given over to 
		unrestrained desire for another. Though yet a matter of the mind it is 
		called what it is – sin.
		
		The Lord is not dealing 
		here with the mere momentary passing of desire through the mind; 
		otherwise there would be no distinction between temptation and sin. (We 
		should not be aghast at the suggestion that the lust of the flesh might 
		have made its approach to the mind of our Savior while He remained 
		sinless, 
		
		Hebrews 4:15.) The 
		words, “looks at a woman to lust for her,” help us to understand the 
		exact nature of the transgression. This is not a fleeting thought but 
		the gathering up of one’s mind for the purpose of lusting. The Greek 
		text describes a person who directs his thoughts or turns his mind to a 
		thing; in this case, lusting after a woman (or a man). Obviously, we do 
		not look at everything we see. The eye takes in a vast panorama and it 
		is left for the mind to focus the attention. David’s sin was not in 
		seeing the unclothed Bathsheba but in looking upon her, setting his mind 
		and ultimately his unbridled lust upon her 
		(2 
		Samuel 11:2-5). 
		David wanted the opportunity to possess Bathsheba, and found it. His 
		violation of 
		Exodus 
		20:17 would have 
		been no less had that opportunity never presented itself.
		
		Although the English word 
		“lust” accurately connotes the sensual overtones of the Greek verb (epithumeo), 
		it may lack the attendant thought of possession which is inherent in it 
		(Guelich, The Sermon on the Mount, p. 194). The sin being described by 
		Jesus is the calculated cultivation of the desire to possess one to whom 
		you have no right. If this sin is to be escaped, the very first approach 
		of such thoughts must be decisively rejected, before they can take 
		possession of the mind and will. In the language of an old proverb: “You 
		cannot keep the birds from flying over your head but you can keep them 
		from building a nest in your hair.” If we find difficulty in 
		distinguishing between the temptation and the sin in this case it is far 
		wiser to err on the side of caution than on the side of recklessness.
		
		The war of the kingdom 
		citizen with lust in these times is destined to be severe and 
		hard-fought. We are not going to easily escape the miasma of 
		lasciviousness, fornication and adultery that has descended on this 
		generation. Let no disciple be smug 
		(1 
		Corinthians 10:12). 
		There are no societal restraints to lean on. Our strength and defense 
		must reside wholly in our own deep and unshakable resolve to keep 
		ourselves pure for the Lord’s sake. In the final analysis that is where 
		the issue of our faithfulness in the kingdom has always been decided. 
		“Keep your heart with all diligence, for out of it spring the issues of 
		life” 
		
		(Proverbs 4:23).
