How is God involved in our transformation as believers?

In 2 Corinthians 5:5, Paul highlights that it is God who has wrought us for transformation and has given us the 'earnest' of the Spirit. This means that the Holy Spirit serves as a down payment or guarantee of our future state in glory. Our change from being dead in sin to being alive in Christ is a work of divine grace; it is not achieved by our efforts but is initiated by God. The Spirit works within us to foster growth in holiness and a desire to live for Christ. This transformation is essential, for believers are called to become new creations in Christ, reflecting His likeness as we anticipate the final day of renewal.
