Translation, maybe?

Hi,

Now this is REALLY off-topic.
Would you maybe explain the lyrics of the following song:

As english is not my mother´s tongue, i don´t get the meaning of it.

I was at my weakest state
And you kept pushing me on
You gave me something to believe in
And it keeps me standing strong
These lessons that I’ve learned
These things I’ll carry on
And when you’re gone I’ll honor you Each day, however long

This glimmer of hope was never enough
To guide me through the darkness like a diamond In the rough
I held out for and I received
A pain that never left with no reprieve
Like a toast at a table where resentments run free
There can’t be any truth where there’s no honesty

Like an apple from the tree
You were lock jawed in your ways
A reminder of myself in those long forgotten days
Thought you’d stayed off my path
But I just couldn’t see that the blood that’s in your veins Is the same that runs through me

This glimmer of hope was never enough
To guide me through the darkness like a diamond In the rough
I held out for and I received
A pain that never left with no reprieve
Like a toast at a table where resentments run free
There can’t be any truth where there’s no honesty

I had it all but lost my faith
And then you lead me to it
Today I’ll carry on
I had it all but lost faith
And now I’ve renewed it
These things I’ll carry on

Some passages seem to me like it´s about something like finding the sense of life in the own child, but the refrain?!
hm....

Thanks!
