What does it mean that only believers can truly praise God?

The psalmist indicates that true praise is reserved for those who have been chosen by God and have received the gospel's revelation. This highlights a key aspect of sovereign grace theology: that true worship is not merely a ritual but arises from an experiential knowledge of God's saving grace through Christ. Those who are part of the church, symbolized by Zion, have the privilege and capacity to access God through Jesus, emphasizing that our praises are inherently linked to His grace and the understanding of our redemption.
