"If you are worrying about something. It could be anything. I am curious this doesnt sound like the work of the Lord. To me sounds like the devils work"Fred.
All eveil is the work of the devil..but worry...that is a natural feeling..it can save our lives..but I like to call the word 'Concerned'

I'm very concerned about my slow students not passing...so I work extra hard with them.I'm concerned about losing my truck key while hunting so I carry a hidden spare..I'm concerned about how real H E L L is so I strive to know him lest I hear those dreadful words." Depart from me ..I never knew you."Most of the time angels appeared to saints..they normally always said,"Fear Not." because it our natural tendency to fear the unknown. The wise man sees the danger ahead and prepares himself..the fool continues head long into danger. Fear is a good motivator..
However; we have the resources not to be eatten up with concern , anxiety or fear..our help cometh from the Lord..and daily as our relationshipwill grow from worry and eventually get replaced by trust...trust will grow into rest, love and peace.

,"Learn of me,for I am meek and lowly and ye shall find rest in your soul."
