Fret Not (Ps. 37:1)

I was encouraged by the following from my daily reading of Streams in the Dessert. 

Fret Not
This to me is a divine command; the same as "Thou shalt not steal."  Now let us get to the definition of fretting.  One good definition is, "Made rough on the surface."  "Rubbed, or worn away"; and a peevish, irrational, fault-finding person not only wears himself out, but is very wearing to others.  To fret is to be in a state of vexation, and in this psalm we are not only told not to fret because of evildoers, but to fret not "in anywise."  It is injurious, and God does not want us to hurt ourselves. 

A physician will tell you that a fit of anger is more injurious to the system than a fever, and a fretful disposition is not conducive to a healthy body; and you know rules are apt to work both ways, and the next step down from fretting is crossness, and that amounts to anger.  Let us settle this matter, and be obedient to the command, "Fret not."  ~Margaret Bottome

"The branch of the vine does not worry, and toil, and rush here to seek for sunshine, and there to find rain. No; it rests in union and communion with the vine; and at the right time, and in the right way, is the right fruit found on it. Let us so abide in the Lord Jesus.

~Hudson Taylor

“Worry is the antithesis of trust. You simply cannot do both. They are mutually exclusive.”~Elizabeth Elliot
