How do we know faith is a miracle?

Faith is often regarded as a miracle in the Reformed tradition because it is solely a result of God's grace. Romans 10:17 tells us, 'Faith comes by hearing, and hearing by the word of God.' This shows that it is not a matter of our own decision or strength, but rather God's work in our hearts that enables us to believe. The nobleman's belief in Jesus' word (John 4:50) emphasizes that the genuine miracle is the inner transformation that prompts individuals to trust in God despite not seeing physical evidence of His work.
