I tried to chase you down
I tried to see how low I can get down to the ground
I tried to earn my way
I tried to tame this mind
You better believe that I tried to beat this
So when will this end
It goes on and on
Over and over and over again
Keep spinning around I know that it won't stop
'Til I step down from this for good
I know that God is good. I have experienced God's goodness. Yet there is nothing in me that is naturally good. I know intellectually that purity is worth pursuing yet a major part of me still desires everything that is impure.
God has saved me yet there is still much work to be done in my heart and mind. This is purposeful.
I might try with my own energy to live sinlessly for one day, but this is impossible. That I would set such a goal for myself proves that I am distracted. We might imagine that God's goal for us is that we avoid sin. But God requires much more than that.
As implied at the end of Sick Cycle's chorus, we will gain freedom from sin when we die. This is true both right now as well as later on when we die from old age.
God requires His people to die in Christ right now. Death from old age is only one more step in our eternal calling.
Gaining freedom from sin is part of the lifelong process of following after Christ. Either through hardship or through rest (usually hardship) our Rabbi teaches us to desire good.
The more we eat and drink Christ the less we will desire imitation fillers. In the same way that it makes sense to eat bread more often than cotton candy, so also it makes sense to eat and drink Christ rather than whatever the world has to offer.
There is an immediate advantage to acknowledging our addiction to sin. A true realization of our inbred wickedness will drive us to depend completely on God's Spirit (rather than our own intellectuality or physical strength).
