"You and I are creatures of desire. There is nothing you ever choose, do, or say that is not the product of desire. Desire not only directs your choices, it shapes your dreams. Desire forms your moments of greatest joy and darkest grief. Desire makes you envious of one person while being glad you're not another. Desire keeps you awake at night or puts you soundly to sleep. Desire makes you willing to get up in the morning or causes you to be frustrated at the end of the day. Desire makes you expectant and hopeful in one moment, and demanding and complaining in the next. Desire sometimes makes you susceptible to temptation and at other times is the thing that defends you against it. Desire can lift you up to God or it can make you a willing friend of the devil.
Desire for him was intended to shape all the other desires that we would rightly have. You see, it is not wrong to desire comfort, acceptance, peace, success, order, health, etc... In fact, there would be something wrong with you if you did not desire these things in some way. But these desires must never rule you, because when they do they replace God as the ruler of your heart. The move from desire to idolatry is a shockingly short step.
So, we all need to cry out for help once more, we all need to seek God's rescue and his power, because we must all humbly admit that there is evidence in our daily living that the war of desire still rages in our hearts. There are times when Jesus is our priceless treasure, but there are other times when we would rather have other things than him. This means that we cannot quit seeking his help until the day when we are able to say with complete singleness of heart, "...There is nothing on earth I desire besides you." "
