Only Human

This could be unsung before I reach that hell
You trust in me, I'll trust in you
But remember, I'm only human

Before you lose your faith in me
Before you doubt
Before you lose your faith in me
Please hear me out

Two seconds or a lifetime
Do they compare?
I've lost nothing to "before"
But remember, I'm only human

You really think I would waste my time?
Am I impure?
