Will Power

It keeps me knocking at the door,
It hits me heavy like a boar.
It leaves empty like before but I keep my head beside the lord.

We have a plan as we know we can but has there been another man?
I hold my breath and exhale the air...
Could she be that little mare?
All these males and females dare to test the one who says they care.

Still it keeps me knocking right through the roof...
What is the power and what is the truth?
