In the Old Testament the Holy Spirit came upon selected servants for specific commissions rather than dwelling within all of God's people, prompting Moses to express the longing that the Lord would put His Spirit on all His people. This promise receives its initial fulfillment when Jesus Christ pours out the Holy Spirit on the church at Pentecost. Peter, led by the Spirit, quotes Joel 2:28-29 to identify the event, declaring that the same Spirit formerly given only to patriarchs and prophets is now offered to every believer whom God calls. Being filled with the Holy Spirit consistently produces a clear witness to Jesus Christ. In nine recorded instances the immediate consequence is bold proclamation of the gospel, whether through the apostles at Pentecost, Peter before the Sanhedrin, Stephen's vision, Paul's confrontations, or the Antioch disciples' continued preaching. The Spirit's presence is therefore evidenced not by showy gifts but by repentance, humility, and Christ-like service that equips every member of the royal priesthood for ministry. Joel's prophecy began to be realized in a limited way at Pentecost as a type of the church age; its complete fulfillment awaits the Millennium, when the Spirit will be poured out universally after the Day of the Lord. Until then the church is called to live by the indwelling Spirit in faithful, active preparation for that future outpouring.

Jesus Christ launched His church at Pentecost by filling His disciples with the Holy Spirit, demonstrating divine power that enabled them to perform mighty and wondrous acts in service to His purpose and to their brethren. This filling equipped the apostles with the spiritual gift of speaking in tongues, allowing them to communicate the gospel in the recognizable languages and dialects of those gathered in Jerusalem. The same filling fulfills the promise that disciples would receive power when the Holy Spirit comes upon them to serve as witnesses to the ends of the earth. The Holy Spirit continues to distribute spiritual gifts to each of God's chosen people individually as He wills, according to the grace given, so that every member possesses at least one such gift. These gifts, termed charisma, manifest as free, unmerited endowments that enhance natural talents or impart new abilities for spiritual aims, including prophecy to proclaim God's Word, healings to restore physical health, leadership to galvanize others, and service to provide aid. In the Old Testament, God filled individuals with His Spirit for specific purposes, granting Bezalel wisdom, understanding, knowledge, and workmanship for the Tabernacle, Moses the ability to perform miracles, Joshua strength and courage, Samson physical power, David a godly heart, Solomon wisdom, Isaiah pure lips, Jeremiah courage to speak, Ezekiel implacability, and Daniel and his companions wisdom and understanding. Such filling by the Holy Spirit ensures that gifts, whether visible like speaking or writing or less noticeable like organizing, advising, praying, or encouraging, are present and useful for carrying out God's work. Believers are to identify and employ these gifts fully rather than neglect them, giving freely as they have been received.

Being filled with the Spirit forms the essential condition for Christian submission to one another in the fear of Christ. The Apostle Paul connects this filling directly to the command against drunkenness with wine, which produces dissipation and self-assertion. In contrast, those filled with the Spirit display the opposite character by speaking to one another in psalms, hymns, and spiritual songs, singing and making melody in the heart to the Lord, and giving thanks always for all things to God the Father in the name of the Lord Jesus Christ. This same filling enables voluntary subjection to one another, illustrated by soldiers who relinquish individual control to obey commands for the sake of the whole regiment. Without the Spirit no one can practice such submission, which the world neither understands nor performs. The filling produces the fruit of the Spirit, including love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, and self-control, so that believers willingly set aside thoughtlessness, selfishness, self-assertion, opinionated pride, and hypersensitivity. It also opens the understanding to the truth about personal sinfulness and membership in one body, prompting each person to esteem others and consider the good of the whole rather than individual rights. This principle governs relationships within the family of God, including those between husbands and wives, parents and children, and servants and masters, always carried out in the fear of Christ.
