We we go to God in worship we are to go joyfully. This means we should be enthusiastic when we worship Him. God is the Creator and we belong to Him. Because God’s goodness is everlasting, we all are to rejoice in His presence.
Be happy with who God is and with everything He does. Don't be afraid to let everyone know about how good God is and Him and His word is constant and NEVER changing.
Make a joyful noise unto the LORD, all ye lands.
Serve the LORD with gladness: come before his presence with singing.
Know ye that the LORD he is God: it is he that hath made us, and not we ourselves; we are his people, and the sheep of his pasture.
Enter into his gates with thanksgiving, and into his courts with praise: be thankful unto him, and bless his name.
For the LORD is good; his mercy is everlasting; and his truth endureth to all generations.
