How do we know that God convicts sinners of their sin?

The conviction of sin is a work of God's Spirit and is often expressed through the preaching of His Word. In Habakkuk 3:16, the prophet describes the overwhelming effect of hearing God's voice—his body trembles, indicating a deep sense of conviction. This theme is echoed in the New Testament, particularly in Acts 2:37, where those who heard Peter's sermon were 'pricked in their hearts,' prompting them to seek salvation. The Holy Spirit works in the hearts of individuals to expose sin and reveal the holiness of God, leading to a realization of one's need for a Savior. Recognizing our sinful state is the first step toward finding rest in Christ, whose sacrifice makes atonement for sin.
