How does salvation come out of Zion?

According to the sermon, salvation comes out of Zion because the Church is established to bear witness to Christ and preach the gospel. This act of preaching serves as the means through which God calls His elect out of darkness into the light of Christ. The Church, as the pillar of truth, upholds and proclaims the righteousness that is found in Christ alone, leading to the regeneration of believers. Therefore, the work of salvation is inherently linked to the ministry of the Church, which fulfills the promise of God to bring near His righteousness for the salvation of His people.
