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

The truth of the fruit of the Spirit can be seen in the lives of those who have experienced the regeneration through the Holy Spirit. According to Galatians 5:22-23, the characteristics of love, joy, peace, and goodness are not merely human efforts but the result of spiritual transformation. The Holy Spirit works within believers to produce these qualities, marking them as new creations in Christ, as emphasized in 2 Corinthians 5:17. This transformation is a testament to the power and truth of the Spirit's work in our lives.
