This Mortal Coil

This mortal coil is fertile soil
for sin without and in
And with a sigh we wonder why
we seldom run to Him

When first we find ourselves intrigued
like moth unto a flame
Then when consumed and sorely grieved
we run to Him in shame

Confessing time and time again
the same besetting sin
And seeking somehow to explain
because we cannot win

The battle's not to swift and strong
for flesh and blood agree
That mind and spirit have been long
held in captivity

When will we learn that standing firm
defeats our enemy
While fleeing sin we run to Him 
His Spirit sets us free
