How do we know Jesus purchased our salvation?

The doctrine of redemption asserts that Jesus purchased salvation for His people through His sacrificial death. In 1 Corinthians 6:19-20, it is proclaimed that we are not our own; we were bought with a price, specifically the precious blood of Christ, as noted in 1 Peter 1:18-19. This transaction highlights the grace and the cost of our salvation, revealing God's intention to claim us as His own. Therefore, our salvation hinges not on our actions but on the completed work of Christ, who provided for our redemption fully and completely.
