So you tolerate his sin, so that you look good.
Ok then...
1. My father once said "Where there's love there is good." My father RARELY said stuff like that. But he was right. My nail guy and his (now dying of brain cancer) partner have love.
2. I don't judge them. Who am I to judge? I remember the movie SON OF GOD and the scene with the woman about to be stoned for adultery. Jesus told them: Whoever is without sin--cast the first stone.
Besides, I am old and was never more than "attractive" in my twenties. My nails were always thin and brittle, always splitting. I had HORRIBLE nails. I still do under these nail tips.
Then one day, my girlfriend, who always bit her nails to the stubs showed up with GORGEOUS nails...yes, artificial nails. So I got them too. I get my hair cut and colored too.
I spend VERY little money on my appearance: clothes by L.L. Bean but I taught at the college level most of my working life and it was a good thing to be well groomed. Hair and nails are all I do. I haven't worn make up for almost 50 years and I wear no jewelry except very simple small hoops.
Looking good -- lol. My dear, sweet husband thought I was beautiful and I DID ask him if he needed glasses but ... I was lucky to have such a husband. I miss him still.
Tolerate sin? You are harsh and wrong. I simply don't judge people and TRY to take them at face value.
