I'm better than I was

 but not where I want to be.

I'll never be fully satisfied 

 while I'm in this fleshly body.

Probably. 

but I do have a dream

 though it's impossible it seems  -

I want to be so much like Jesus 

 you can't tell if it's Him or if it's me

....but I'm running out of years

I'm trying to be sincere  -

I need to surrender all my heart

not just part

and not put on an act with a few tears
