in my day, girls weren't encouraged to study math. So your exhortation to
go back to geometry 101 is useless... never had it. so what am I doing on
a scientific bbs, you ask? trying to learn to see things a little
differently, and beginning to realize why highly educated people stumble
on the Bible, why so many slide into "liberal interpretation" of
Scripture, why so many are discouraged with trying to understand God. I
wonder if the Word would be distorted if I were to suggest that it is hard
for a rich man - rich in knowledge as well as material things - to enter
the kingdom...
