What does hearing of faith mean in the context of sanctification?

In the context of sanctification, the 'hearing of faith' signifies the process of receiving the gospel message and recognizing God's work in Christ. This is seen in Galatians 3:2, where Paul questions whether the Spirit was received by works or by hearing with faith. True faith is a response to the truth of the gospel, acknowledging that our sanctification is not achieved by our efforts but through the ministry of the Holy Spirit. As believers continually hear the gospel, they are reminded of their position in Christ and are transformed into His image—the essence of sanctification. Therefore, hearing of faith is integral to the believer's growth in holiness.
