How do you rustproof the heart? You simply add a "t" and turn rust to trust.
1 Do not fret because of those who are evil
or be envious of those who do wrong;
2 for like the grass they will soon wither,
like green plants they will soon die away.
3 Trust in the LORD and do good;
dwell in the land and enjoy safe pasture.
4 Take delight in the LORD,
and he will give you the desires of your heart.
5 Commit your way to the LORD;
trust in him and he will do this:
6 He will make your righteous reward shine like the dawn,
your vindication like the noonday sun.
7 Be still before the LORD
and wait patiently for him;
do not fret when people succeed in their ways,
when they carry out their wicked schemes.
8 Refrain from anger and turn from wrath;
do not fret—it leads only to evil.
9 For those who are evil will be destroyed,
but those who hope in the LORD will inherit the land.
10 A little while, and the wicked will be no more;
though you look for them, they will not be found.
11 But the meek will inherit the land
and enjoy peace and prosperity.
