Where the real joy come from?

   Joy is a very serious matter for a Worshiper. And a serious  Worshiper seeks to align to the truth of the Scripture, wholeheartedly.

It's not a suggestion in the Word of God, but a command:

Rejoice evermore. 1Thess.5:16

Rejoice in the Lord, you who are righteous, and praise his holy name. Psalm 97:12

You have loved righteousness and hated wickedness; therefore God, your God, has anointed you above your companions with the oil of joy. Psalm 45:7

   It's important not to confound simple fleshy excitement and enthusiasm with a joy, which flows from obedience.  Here you can only see joy bursting out, but the real foundation (which you don't see) is letting go of endless demands and control of the flesh.

                                                                               Let them go... you'll be so glad you did.
