One of the clearest evidences of a Spirit-filled Christian is his hunger for Scripture and his humble submissiveness to the authority of Scripture as God’s written Word. But show me a person who claims to be a Christian yet is not devoting himself to the apostles’ teaching, who rather neglects and even disregards it, and you give me cause to question whether he has received the Holy Spirit at all. For the Holy Spirit is the Spirit of truth (as Jesus called him). He is given us to be our teacher, and those who are filled with him have a keen appetite for his instruction.
