This psalm of praise and thanksgiving calls on all the earth to make a joyful shout to the LORD. We are to serve gladly and come before Him with singing. He is worthy because He is our Creator and the Good Shepherd! We are to give thanks in all situations and not only for the many bountiful blessings we can see, but those that are unseen! The LORD is good! His mercy endures forever! His truth endures to all generations! Hallelujah!!!
