what does the bible say?
The Bible teaches that the Holy Spirit regenerates, infills, and indwells believers. But only belief in Christ saves, not theological knowledge. Both the Old and New Testaments testify to the Holy Spirit's work. The Holy Spirit regenerates believers (Deuteronomy 30:6; Jeremiah 31:33; Ezekiel 11:19; John 3:5). After someone accepts Christ as Savior, he or she is permanently indwelt by the Holy Spirit (Ephesians 1:13). But Scripture is clear that only belief in Christ saves (John 3:16; Acts 16:30-31; Romans 3:28). Knowledge is a work, and works do not save (Ephesians 2:8-9). If someone has little to no knowledge of the Holy Spirit's presence in believers' lives, that lack of knowledge will not prevent the person from being saved if they believe in Christ. This differs from rejecting the Holy Spirit. The Bible indicates, though, that believers will want to learn more about God, which implies learning about the Holy Spirit (2 Peter 2:2; cf. Hebrews 5:12-14).
