What does the Bible say about God's grace and salvation for sinners?

In Isaiah 65, we see God's grace vividly portrayed, revealing that He saves sinners who aren't even seeking Him. This underscores the sovereignty of God's grace, as it is not based on human merit. The passage illustrates that God stretches out His hands to those who rebel against Him, demonstrating His mercy to unworthy individuals. This beautifully aligns with the doctrine of sovereign grace, affirming that salvation is solely through God's initiative, not dependent on our righteousness or efforts.
