How do we know that salvation is a miraculous work?

The concept of salvation as a miraculous work is rooted in the Scriptures, especially in 1 Corinthians 3, where Paul clarifies that neither the one who plants nor the one who waters is anything, but it is God who gives the increase. This underscores the sovereignty of God in the process of salvation. It is not about human ability or effort but rather God's purpose and action that lead to the saving of souls. This divine aspect of salvation emphasizes that it is a gift from God, given according to His grace and mercy, not dependent on human merit.
