What does the Bible teach about the role of the Holy Spirit in salvation?

In Scripture, the role of the Holy Spirit in salvation is depicted as essential for both drawing individuals to faith and enabling genuine transformation within believers. John 6:44 states that 'no man can come to me, except the Father which hath sent me draw him,' emphasizing the Holy Spirit's active role in this process. Moreover, true repentance, as a work of the Holy Spirit, is not something one can fabricate; it is the result of divine intervention in the believer's heart. This underscores the necessity of relying on the Holy Spirit rather than human efforts to bring about genuine faith and repentance.
