What does the Bible say about God's grace in Josiah's life?

In Josiah's life, we see a profound example of God's sovereign grace at work. Despite being the son of the wicked king Ammon, who rejected the ways of God, Josiah was chosen by God unto salvation even before he was born. God's grace was operative in Josiah's life from eternity, as he was under the watchful care of his heavenly Father, who sought to bring him to faith in the right time. This reflects the Reformed understanding of grace that emphasizes God’s initiative in salvation, demonstrating that we are God’s children not because of our works, but because of His divine election and calling to each of us.
