Evidence of the Holy Spirit's personhood is found in His actions and qualities ascribed to Him in Scripture.
We establish the personhood of the Holy Spirit through several doctrinal proofs presented in Scripture. First, the Holy Spirit has personal attributes such as understanding and will. For example, 1 Corinthians 2:10-11 emphasizes how the Spirit searches all things, revealing knowledge to believers, a distinctly personal action. Additionally, Acts 5:3 speaks of lying to the Holy Spirit, suggesting awareness and agency indicative of personhood. The Holy Spirit embodies acts of power, regeneration, and communication, proving His existence as a person who engages in relationships with believers and moves within them, shaping their spiritual lives.
