Is there a double meaning for Hagar being cast out?

I have seen often times among charismatic movement, the slain of the Spirit. Is this Scripture with reference?

So, I'm reading the book of Ruth, I was wondering if that book is covered anywhere here on the site, for further insight?

We have have a person of a negative effect in our lives or sooner or later we will meet one. As a Christian is it worth enduring their negative attitude?

I know we are cover by Grace, but are still to confess our sins. Does this apply to temptation too?
