Thankful To Whom?

“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” (Psalm 100:1-5 KJV).
