How does the Holy Spirit help in sanctification?

The Holy Spirit plays a crucial role in the sanctification process by being the efficient cause of this transformative work in believers' lives. 1 Thessalonians 2:13 points to the inherent power of God's Word as the instrument through which the Spirit works. As believers engage with Scripture, the Holy Spirit helps them to apply its truths, shaping their hearts and minds in accordance with God’s will. Moreover, the Spirit empowers believers to resist sin and pursue holiness, as indicated in Galatians 5:22-23, where the fruits of the Spirit manifest in the lives of those who walk by the Spirit. Thus, His presence is indispensable in realizing the ultimate goal of sanctification: conformity to the image of Christ.
