Our trials are designed to wean us off fretting as we rest in the Lord....
Psalm 37 (NKJ)
A Psalm of David.1 Do not fret because of evildoers,
Nor be envious of the workers of iniquity.
2 For they shall soon be cut down like the grass,
And wither as the green herb.
3 Trust in the LORD, and do good;
4 Delight yourself also in the LORD,
And He shall give you the desires of your heart.
5 Commit your way to the LORD,
Trust also in Him,
And He shall bring it to pass.
6 He shall bring forth your righteousness as the light,
And your justice as the noonday.
Do not fret because of him who prospers in his way,
Because of the man who brings wicked schemes to pass.
8 Cease from anger, and forsake wrath;
Do not fret—it only causes harm.
