How do we know spiritual gifts are given by the Holy Spirit?

According to 1 Corinthians 12:11, it's clear that the Holy Spirit divides spiritual gifts to each person as He wills. This passage indicates a sovereign act of God where He determines who receives which gifts based on His divine purpose for the church. Each believer is endowed with specific talents and abilities that manifest the Spirit's presence, all aimed at the common good and the exaltation of Christ. Thus, the belief in the giving of spiritual gifts rests not on human effort but on divine sovereignty.
