How do we know the Holy Spirit's witness is true?

The truth of the Holy Spirit's witness is confirmed through the alignment of the Spirit's testimony with our own conscience. Romans 8:16 reveals that the Spirit bears witness with our spirit that we are children of God. This dual witness provides believers with profound assurance, as it reflects an internal reality validated by God's Word. When a believer's heart resonates with the truth of salvation and grace, it signifies the Holy Spirit's definitive role in affirming their confidence in eternal life.
