I don’t think I will ever think less of you, but it would be fun for you to go all the way to worst-case scenario and assume that I will.
That takes away the external approval. Even go all the way to assuming that your kids push you away and don’t stay connected to you when they grow up.
Still, are any of those a reason to turn on yourself? Whose job is it ultimately to love you no matter what? Isn’t that the place where all the rest can come and go and everything is OK, where you’re not dependent on anything showing up any particular way.
Unconditional means without conditions. I think our goal is to get closer and closer to loving ourselves the way God (who created and sustains us and is never separate from us and is love) loves us.
