Rejoice in the Lord!!

This is one command that God issues over and over in the Bible that I have great difficulty with. I don't have trouble abstaining from murder, adultery, fornication, idolatry, etc... But, I often find great difficulty rejoicing in the Lord. I worry, doubt, forget, and often find myself on the edge of depression when things don't go the way I see them going. WOW!!

How much freedom exists in rejoicing in Him? How much hope exists in rejoicing in Him?

Lord help me to focus on you and not me... and rejoice!

Psalm 97
1 The LORD reigns, let the earth be glad; let the distant shores rejoice. 2 Clouds and thick darkness surround him; righteousness and justice are the foundation of his throne. 3 Fire goes before him and consumes his foes on every side. 4 His lightning lights up the world; the earth sees and trembles. 5 The mountains melt like wax before the LORD, before the Lord of all the earth. 6 The heavens proclaim his righteousness, and all the peoples see his glory. 7 All who worship images are put to shame, those who boast in idols—worship him, all you gods! 8 Zion hears and rejoices and the villages of Judah are glad because of your judgments, O LORD.
9 For you, O LORD, are the Most High over all the earth; you are exalted far above all gods.
10 Let those who love the LORD hate evil, for he guards the lives of his faithful ones and delivers them from the hand of the wicked. 11 Light is shed upon the righteous and joy on the upright in heart. 12 Rejoice in the LORD, you who are righteous, and praise his holy name.
