How does Isaiah 6 relate to the New Testament understanding of salvation?

Isaiah 6 is intrinsically related to the New Testament understanding of salvation as it illustrates the process of divine revelation, recognition of sin, and the provision of atonement. Just as Isaiah experienced purification through the live coal from the altar, which represents Christ's sacrificial work, New Testament teachings emphasize that Christ's atonement is what cleanses us from sin. Furthermore, Isaiah's call to obedience, 'Whom shall I send?' is echoed in the Great Commission where believers are sent to proclaim the gospel. This connection underscores the continuity of God's redemptive plan from the Old Testament to the New Testament, showcasing that salvation has always been a work of God’s grace.
