Welcome to CC, sister Susan. It was a shame about how Lewis' Susan thought she had outgrown the simplicity of the Gospel. We must help each other withstand the temptation to become proud, haughty, and self indulgent. I know and understand how God has placed many things in my life to keep me humble. Even Paul needed a thorn in the flesh.
So glad you came. We have a few uglies hiding behind the trees here in CC Land also, but don't let them discourage you. Bless you dear, and Godspeed!
