How does God save sinners according to the sermon?

According to the sermon, salvation is an act of God's sovereign grace, initiated by His election of certain individuals. It is through the covenant union with Christ that believers are justified and receive new life. This means God elected a people for Himself, formally establishing their salvation in the covenant made with Christ, whereby Christ lives a perfect life for them and dies to atone for their sins. The gift of faith is then granted by God to the elect, enabling them to respond to the gospel. This underscores that salvation is completely an act of God’s grace and not something we can achieve on our own.
