What does Psalm 95:3 mean?

Ancient Israel was surrounded by nations who worshipped many false gods. Only the One True God, the Lord of Israel, actually exists (Deuteronomy 4:35; Isaiah 45:21; John 1:1–2). When Scripture speaks of God being greater than other deities, the point is not that the Lord is the best choice among many. It's a reminder that the Lord is the omnipotent Creator, and other so-called "gods" are nothing (Exodus 18:11; Psalm 96:4; Psalm 135:5).

Because He is the One and Only God, the Lord deserves praise. He is the source of everything in creation (Genesis 1:1), so all His attributes are worthy of praise. He loves believers with an everlasting love (Psalm 103:17). His mercy and faithfulness have no end (Psalm 86:15). He is all-knowing and all-powerful (Daniel 2:20). His grace is unlimited (2 Corinthians 9:8). He is attentive to the prayers of His people (Psalm 65:2). He is alongside every believer (Deuteronomy 31:8; Hebrews 13:5). He reigns supreme as King of kings (Revelation 19:16). He is far above all the false gods human beings have created.

When Elijah exposed the false god Baal, the people of Israel fell on their faces and rightly exclaimed, "The LORD, he is God; the LORD, he is God" (1 Kings 18:39). Isaiah 6:1 describes the Lord as "sitting upon a throne, high and lifted up." Revelation 7:9–12 gives readers a view of God as seated on a throne, and a great multitude cries out with a loud voice, "Salvation belongs to our God who sits on the throne, and to the Lamb!"
