How do we know spiritual baptism is true?

Spiritual baptism is evident through the work of the Holy Spirit in the lives of believers, which the Bible explains as a necessary transformation. John the Baptist prophesied that Christ would baptize with the Holy Spirit and fire, signaling a profound internal change (Matthew 3:11). This spiritual baptism is crucial for regeneration, as it opens the heart to truly understand and believe in the Gospel. Romans 8:15 illustrates that believers receive the Spirit of adoption, enabling them to cry out to God as their Father, which affirms their status as children of God. Thus, we see both the promise and the fulfillment of spiritual baptism through faith and new birth.
