The great Reformer John Calvin claimed that this text testifies to "how great is the blindness of the human mind..." (Calvin's Commentaries, Vol. XX/1, p. 396). "Hence it is necessary that we should be directed by the Spirit of God, or we shall wander forever. From this too it follows, that all things that pertain to the true knowledge of God are the gifts of the Holy Spirit" (Ibid., p. 397). The Holy Spirit works all the good things we have in life. All the gifts we have in the ministry of the church are gifts of the Holy Spirit.
