Yeah..I don't think that long-term self condemnation will result with older believers, and it is mostly baby believers I'm concerned with. Maybe that's what Jesus was referring to, when he mentioned offending a little one..or at least part of it.
Matt 18:5 5“Whoever receives one such child in my name receives me,
6but whoever causes one of these little ones who believe in me to sin,
a it would be better for him to have a great millstone fastened around his neck and to be drowned in the depth of the sea.
"receives" has to do with acceptance and not rejection.
