How do we know God works in the hearts of sinners?

Scripture clearly states that the work of regeneration is an act of God, revealing the sinful state and need for salvation. In John 4, we see this in the life of the Samaritan woman; Jesus disclosed her sins, prompting her belief (John 4:16-18). This illustrates that God knows the hearts of sinners intimately and works to reveal His truth to them. Sovereign grace theology holds that God grants faith and understanding, compelling individuals to turn to Him and receive His grace. Such experiences confirm God's active engagement in the hearts of sinners as He draws them to Himself for salvation.
