How do we know that God saves the unbelieving?

God's method of saving the unbelieving is rooted in His divine power and grace. As described in the sermon, one of the key verses supporting this is John 20:27, where Jesus commands Thomas to cease his unbelief and believe. This highlights that salvation is not achieved by human effort but through the intervention and proclamation of the gospel. God reaches out in grace, transforming hearts that are naturally skeptical and unfaithful into those that trust Him. The prevalent theme in Scripture is that it is God who turns the hearts of sinners to Himself, assuring them of their faith through His Spirit. Thus, our conversion is ultimately a testament to God's sovereignty and gracious initiative in overcoming our natural unbelief.
