The term "Filling of the Spirit" in the Bible refers to a profound experience in which a believer is empowered and influenced by the Holy Spirit for service, worship, and living a Christian life. This concept is prominently found in the New Testament, particularly in the book of Acts, where believers are described as being filled with the Holy Spirit (Acts 2:4; 4:31). The filling of the Spirit is often associated with boldness in proclaiming the Gospel, spiritual gifts, and a deeper intimacy with God.Theologically, the filling of the Spirit is distinct from the indwelling of the Spirit, which occurs at conversion (Romans 8:9). Instead, filling is considered a repeated experience, necessary for effective ministry and spiritual growth. Ephesians 5:18 instructs believers to "be filled with the Spirit," implying an ongoing process of surrender and dependence on the Holy Spirit. This filling empowers individuals to live according to God's will, exhibit the fruit of the Spirit (Galatians 5:22-23), and carry out the mission of the Church.
