How do we know that salvation is a creative act of God?

Salvation is indeed a creative act of God, intricately tied to the original act of creation. Just as God spoke the world into existence from nothing, He also brings about spiritual rebirth in His children. In 2 Corinthians 4:6, it is stated that God, who commanded light to shine out of darkness, has shined in our hearts to give the light of the knowledge of His glory. This passage highlights that our new birth is initiated solely by God's sovereign will and power, demonstrating that we are new creations in Christ (as affirmed in 2 Corinthians 5:17). Thus, the transformation from darkness to light is not a human endeavor but rather a divine work of grace.
