What is the significance of the 144,000 in Revelation?

In Revelation 7, the number 144,000 is presented as a symbolic representation of the church, God's chosen people from every tribe and nation. This number signifies completeness and perfection, reflecting the assurance that God knows and has a distinct plan for the salvation of His elect. By numbering the 144,000, the text illustrates God's sovereignty in redemption, affirming that there is a specific group of people whom Christ has redeemed.
