I love the way You love like no other
It's got nothing to do
With anything that I do
God's love is not like anyone else's in that He loves everyone to the same extent regardless of what that person has done. No matter what, God always loves us the same. And that's a very comforting thought.
Even though he has faith in his girl, he still has doubting thoughts that she doesn't actually care about him and isn't responding, making his talking to the moon futile.
