How do we know God’s sovereignty in salvation?

The sovereignty of God in salvation means that He retains absolute control over who receives faith. In John 12:39-40, it explains that many could not believe because of judicial blindness imposed by God due to their rejection of Christ. This illustrates that while humans have a will, God ultimately exercises His sovereign authority over salvation. As seen in Romans 1, when God turns someone over to a reprobate mind, it highlights that God’s decision in matters of faith and belief is not arbitrary but rooted in His justice and mercy.
