Fret not yourself because of sinners

Fret not yourself because of sinners,
For at Judgement day they won’t be winners.
And about workers of iniquity don’t be envious,
Because their end will be truly devious.

Fret not yourself but trust in God,
For then in the land you will trod.
And you will good things be fed,
Because by the Lord you are lead.

Fret not yourself but in Christ delight,
For by him you can win each spiritual fight.
And God will give you your heart’s desires,
Because your faith in him keeps up and fires.
