What keeps you from desiring God?
What on earth do you treasure so greatly that you are willing to trade the limitless joy found in Christ for a brief moment's stolen pleasure?
Believer, your spiritual adoption into the family of God allows you to seek God and to find Him; to drink and never be thirsty again. Think about the wonder in that statement: to drink, and in so doing to forever satisfy your longing. You are granted this access, this satisfaction in God, by birthright; His grace to you has made you His own. You who were once far off have been brought near, and He who was your greatest enemy you are able to call Father, to dine at His table. If your heart of stone has been ripped out and replaced with a heart of flesh, why do you return to your old ways? How, if you have tasted and seen that the Lord is good, can you even once more chose to believe that the spoiled meat which you feasted upon in your former life could fill you up?
The tragedy of the believer's life is that he chooses like a dog to return to his own vomit. Proverbs tells us that this is the mark of a fool: to repeat his folly. It is not enough to eat the spoiled meat of sin once, and being sickened by it, to be necessarily purged of it; the sinning believer willingly puts aside the remembrance of the surpassing greatness of the feast at God's table and goes sniffing back to gnaw at the very thing that Scripture and experience tell him he can not stomach.
The beauty in a believer's life is this: he has tasted and seen that the Lord is good, and therefore what would have satisfied the dead heart inside the walking corpse of the old man can no longer taste the same to a regenerated soul. A believer cannot tarry in sin, to live by that poison. He must, by his new nature, eat the food that gives life, that is, the water and bread of life: Jesus Christ. Christ has transformed your soul from the dead to the alive, has taken your sin on Himself that you may have his righteousness, and has has changed your appetite from the damning to the glorifying. It is because of and through Christ that we are given the promise that we will not be tempted beyond what we are able, and it is by feasting on the life-giving Christ that we are able to deny the cravings of a body that were accustomed to eating filth. Oh set your mind on Him! Find your satisfaction in Christ!
Remember that we are told to work out our salvation with fear and trembling. I understand this to mean that I should be so fearful of harboring any sin against God, or valuing anything before Him, that I will not wait for the purifying fire to come to me, but that I will run to the altar of God, eager to burn away the old poison- and death-loving man; that in order to satisfy my God-breathed appetite for the life-giving, I will pursue Christ as the sole and greatest prize in a race that my life, joy, and eternity depend on.
Will you run with me?
