Me the Sacrifice?

The things that I wish not to do, I do
The things that I wish to do, I don't
The thoughts I ought to have, I don't
The thoughts I ought not to dwell on, I do

It is a great struggle for me, drifting in and out of where I am and where I should be.
A never ending struggle with my inner self, seems like there are two forces at work,
One in me and one outside.
One with a constant still small voice pushing me forward..
One outside giving me thoughts pulling me downward.
I desire in a life of holiness, purity, a godly life yet the urge for a life of pleasure and passion is strong.
So strong often I fall, falling is like second nature or is it first?
Created in the image of God but now barely reflective.
Thoughts, motives and actions,
these shows the real man within.
The battle wages on in the mind.
This is the last battlefield.
The war is over at the cross.
Will I stand with the victors or will I be another casualty?
The witnesses are looking, I am still waiting,
Where are my brothers, my comrade in arms?
Where is the united front?
I feel alone, so alone.
But fight I must, no matter how many times I fall,
I'll fight till it is all over..
It is clear as daylight, either be the living sacrifice or be the dead one.
I choose the former.
The battle goes on...

Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God–this is your spiritual act of worship.
Romans 12:1

For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms.
Hebrews 6:12
