David is the author. The worship of the people of Israel, we get a glimpse into the character of God and how we should rightly respond to Him in worship. The psalmist talks about the amazing things that God has done that show His power, might and responds in rightful worship. Through this psalm 66, we will be challenged to think about what it means to offer God the worship that He alone deserves. We are to praise and worship the Him. We can live joyful lives in light of what God has done. We can be a witness of the truth and power of the gospel to the children watching us. Walk and live to glorify God in all that we say and do. Before the creation of the world, God has had one, big plan to redeem His people as a magnificent display of God’s glory.

It reads in Psalm 66:1-20 NIV
{For the director of music. A song. A psalm.} Shout for joy to God, all the earth! Sing the glory of his name; make his praise glorious. Say to God, “How awesome are your deeds! So great is your power that your enemies cringe before you. All the earth bows down to you; they sing praise to you, they sing the praises of your name.” Come and see what God has done, his awesome deeds for mankind! He turned the sea into dry land, they passed through the waters on foot, come, let us rejoice in him. He rules forever by his power, his eyes watch the nations, let not the rebellious rise up against him. Praise our God, all peoples, let the sound of his praise be heard; he has preserved our lives and kept our feet from slipping. For you, God, tested us; you refined us like silver. You brought us into prison and laid burdens on our backs. You let people ride over our heads; we went through fire and water, but you brought us to a place of abundance. I will come to your temple with burnt offerings and fulfill my vows to you, vows my lips promised and my mouth spoke when I was in trouble. I will sacrifice fat animals to you and an offering of rams; I will offer bulls and goats. Come and hear, all you who fear God; let me tell you what he has done for me. I cried out to him with my mouth; his praise was on my tongue. If I had cherished sin in my heart, the Lord would not have listened, but God has surely listened and has heard my prayer. Praise be to God, who has not rejected my prayer or withheld his love from me!
