Years ago, after I preached about God’s Spirit, a woman came up after church to complain, “Why do you talk about the Holy Spirit when people need to hear about Jesus and God?” Sometimes even those who have been Christians for a long time regard the Trinity as a hierarchy. To their way of thinking, the Father is God, Jesus is slightly beneath Him in rank and seniority, and the Holy Spirit is their servant. While this may conform to human models of authority, it isn’t biblical.
According to the Scriptures, all three members of the Trinity are fully God:
God the Father—Jesus Christ referred to His Father as God (John 5:17-18).
God the Son—John 1:1 identifies Jesus as divine. While Christ never specifically called Himself “God,” His Father did apply the title to Him (Heb. 1:8). Furthermore, Jesus acknowledged having unlimited power—an attribute possessed only by the divine Creator (Matthew 28:18)—and also accepted worship (Matthew 14:33; John 9:38).
God the Holy Spirit—After declaring that God raised Christ from the dead, the New Testament goes on to credit the Holy Spirit with the resurrection (Romans 8:11). Jesus reinforced that idea when He commanded the disciples to baptize new believers in the name of the Father, the Son, and the Holy Spirit.
The Bible confirms that each member of the Trinity is equally God. The Father, Son, and Holy Spirit function as a unit—no one is more important or less essential than the others. All three are focused upon their plan for mankind: salvation, transformation, and glory for God.
