Read between the lines,

If the sun shuts down and decided not to shine no more
I would still have you, baby
If we see the last day and they say we gotta go to war
I'll be fighting with you, baby
Cuz I know if I'm falling, you won't let me hit the ground
If the boat is sinking, I know you won't let me drown.
I love like you more and more with every passing day.
