How do we know that the fruit of the Spirit is real?

The authenticity of the fruit of the Spirit can be discerned through the transformation it brings in a believer's life. Paul writes in Galatians 5:22-23 about the attributes that constitute the fruit of the Spirit, such as love, joy, and peace. These qualities are not merely actions or behaviors but are a reflection of one's inner state, resulting from being connected to Christ, the true vine. Moreover, 2 Corinthians 7:9-10 emphasizes that godly sorrow leads to repentance and exhibits genuine transformation, thus serving as a validation of the Holy Spirit's work in a person's heart.
