Jesus offers a radical solution to the problem of lust - a disordered desire that is a parasite upon love. The solution calls for radical, severe, and resolved discipline. It demands that we guide all our desires by the supreme desire of love for God. "This is not 'repression', as people sometimes suggest. It is more like the pruning of a rose, cutting off some healthy buds so that the plant may grow stronger and produce better flowers. Choosing not to be swept along by inappropriate sexual passion may well feel on occasion like cutting off a hand or plucking out an eye, and our world has frequently tried to tell us that doing this is very bad for us. But, for neither the first nor the last time, we must choose to obey our Lord rather than the world." (N. T. Wright).

Matthew 5:27-32 "You have heard that it was said, 'You shall not commit adultery.' 28 But I say to you that everyone who looks at a woman with lust has already committed adultery with her in his heart. 29 If your right eye causes you to sin, tear it out and throw it away; it is better for you to lose one of your members than for your whole body to be thrown into hell. 30 And if your right hand causes you to sin, cut it off and throw it away; it is better for you to lose one of your members than for your whole body to go into hell »more

What could be so wrong with a hungry man turning stones into bread? This temptation is not nearly as benign as it initially seems. The tempter seeks to influence Jesus to allow immediate desires to overshadow ultimate concerns - to allow fidelity to God to fade into the background because of the pressing needs of the moment.
In the story of Cain and Abel, we discover that sin is a very real threat to human flourishing. Our freedom is found in obedience to God's counsel. Our struggle against sin is a lifelong challenge. A good society begins with good people. Cain's social injustice is fueled by Cain's personal sin - sin Cain refuses to acknowledge and restrain. 
In the Song of Songs - just as in the opening chapters of the Bible - we encounter a man and a woman in a garden, naked and unashamed. Just as in Eden, God pronounces a blessing on the delightful and fulfilling love of eros. Our human experience of eros is a faint glimpse of God's passion for us. Only eros can communicate the intensity of divine love. 
Eros is passionate love. The deep feelings that accompany eros are often exclusively associated with sexuality, but eros is not limited to it. Though eros is motivated by self-interest, one should not conclude that eros is always selfish. Eros, when rightly ordered with the other loves, is a deeply spiritual expression of love.
Had Jesus desired to do so, he could have satisfied his physical thirst. However, Jesus’ desire for water, for relief from his pain, was not as great as his desire to redeem humankind. In other words, Jesus’ thirst for us trumped his thirst for water. “I thirst” is not simply identification with human pain, but an expression of God's passion for humanity's redemption.
