What does Psalm 95:1 mean?
The term "rock of our salvation" describes the Lord as protecting and delivering His people. In the ancient world, large stones were the most reliable foundations for a building. Rocky areas and mountains were ideal fortresses. That God is a "rock" implies that nothing can be more secure than Him (Deuteronomy 32:4; 1 Samuel 2:2; Psalm 18:2, 31).The book of Ezra describes Israelites returning from exile to rebuild Jerusalem (Ezra 1:2–4). As they laid stones for the foundation of a new temple, there was loud praise and worship (Ezra 3:11–13). This was appropriate; God had blessed them and provided them with hope for the future.
Believers today have assurance that our salvation is secure in God (John 10:28; Ephesians 1:11–14). This ought to inspire calm hearts capable of intense praise.
