What is the difficulty with the second line? I am curious. My thought is that we spend a lot of our life seeing ourselves as others see us. It can be the loving mother or the critical mother. It helps us blossom or close ourselves off to protect ourselves from hurt and disapproval. When you see yourself through the eyes of God you will be humbled and overwhelmed. His love heals and grows you and changes you forever. I spent too many years seeing myself through the eyes of someone who didn't love me. It isn't that I didn't have an individual view of myself but it was life giving to instead, see myself through the eyes of dear friends who did love me and reflected back hope and kindness. That was my thought with the second line.
Well I think there is a distinction between what it means for you, and for her (and others, no doubt).
Also notice the difference in wording that changes the meaning. You phrased it "the eyes of Someone that loves you" vs Mez saying "the eyes of the one that loves you". Two different meanings.
You jumped straight to mother, God, friends but those are not the only options.
I, for example, have issues with seeing myself positively, therefore when in a relationship I have a hard time understanding how I'm viewed by the person I'm dating. They may express it to me and I may know all the right reasons, technically, yet I still can't internalize it and really "get it".
I grew up with good parents, and despite the inability to grasp why someone may feel strong romantic feelings for me, it's easy for me to believe and understand why a parent loves me. So different types of relationships come with varying capacities to understand.
Others may grow up being actively told all their faults, so when people come along that see the good things in them they may have difficulty accepting the idea there is anything good in them for someone to see and enjoy.
So the ability to see how others see you isn't a one size fits all ability.
