Have you ever had the feeling that you want to help someone so much but can't? Not because you don't want to, but because you don't have the capacity to do so. These are my sentiments and maybe yours too when your capabilities aren't the right ones to help the ones you love. 

But if I had these powers, I only have one answer for my beloved wife. 

If I could walk those steps so you won't need to break, I would.
If I could digest what you can't eat so you can taste, I would.
If I could shed your tears so you won't need to weep, I would.
If I could offer my arm so your veins won't bruise, I would. 

If I could share your pain so you'll feel less of it, I would.
If I could free you from your sadness and anxiety, I would.
If I could do all this for you in an instant, I would.

I would simply because I would do anything for you. I would.
