How do we know the indwelling of the Holy Spirit is true?

The doctrine of the Holy Spirit's indwelling is affirmed by the promise Jesus makes in John 14:16-17 where He states that the Spirit will abide with believers forever. This Scriptural promise serves as foundational evidence for the belief in the indwelling presence of the Holy Spirit in the lives of Christians. Additionally, the transformative and sanctifying work of the Spirit acts as confirmation of His presence, empowering believers to live according to God's truth.

Furthermore, personal experience plays a crucial role in confirming the Holy Spirit's indwelling. Believers often experience a deep connection to God, an awareness of His truth, and a conviction that draws them closer to Him. The Spirit helps in understanding and applying the Word of God and brings about genuine change in character—evidence that He is at work within. This personal assurance, combined with the Biblical testimony, solidifies the understanding of the Holy Spirit residing within each believer.
