How do we know God's grace is personal?

The personal nature of God's grace is illustrated in the account of Saul's conversion, where only Saul heard the voice of Christ and experienced His presence. This distinction emphasizes that spiritual revelation and transformation are not given universally but are bestowed upon whom God wills. This aligns with the biblical doctrine that salvation is a gift of grace, personal and specific, not something that individuals can obtain on their own accord. Therefore, God's dealings with us are marked by His sovereignty and personal touch.
