The Holy Spirit bestows unique spiritual gifts upon believers for the purpose of serving others and strengthening the church community. These gifts, including wisdom, knowledge, faith, healing, and prophecy, all flow from one Spirit but manifest differently in each person. While doubt and fear often hold people back from utilizing these gifts, the key is understanding that effectiveness comes from God's power, not personal ability. The focus should be on making ourselves available as vessels for God's work rather than questioning our capabilities.
