Psalms 100:1-5
1 Make a joyful noise unto the LORD, all ye lands.
2 Serve the LORD with gladness: come before his presence with singing.
3 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.
4 Enter into his gates with thanksgiving, and into his courts with praise: be thankful unto him, and bless his name.
5 For the LORD is good; his mercy is everlasting; and his truth endureth to all generations.
This is a short chapter. It is simple. Be thankful to the lord. Be happy when you serve him. He made us. He created us and gave us a living soul. He is the truth. He is our everything. The truth of his mighty power is eternal. He has been the same through all the generations. It is that simple. It is beautiful. God is so amazing.
