God's Indwelling Spirit

The Holy Spirit, as the third person of the Trinity, is essential for Christian living and not merely an optional aspect of faith. As a divine person who thinks, feels, and acts, He permanently indwells every believer, making them children of God and transforming their character. The Spirit provides spiritual life, empowers resistance against sin, and produces spiritual fruit in believers' lives. His presence is evidenced through character transformation, desire to please God, and growing Christ-likeness.
