What does the Bible say about who believes?

The Bible presents a clear dichotomy between those who believe and those who do not. In Acts 13:48, it is stated, 'As many as were ordained to eternal life believed.' This suggests that believing is not simply an exercise of will but rather a result of divine ordination. The concept is further supported in the narrative of Paul's preaching, where the response of the Gentiles shows that genuine belief is intertwined with God's sovereign grace. Belief is thus a fruit of God's work in the hearts of those He has chosen.
