Paul and Peter both declare that the Holy Spirit is the one who inspired every word written in Scripture (Eph 3:4-5; 2 Pet 1:20-21). God’s Spirit inspired the Scriptures to aid the believers in their spiritual understanding and growth (2 Tim 3:16-17). In John 16:13, Christ tells the disciples that the Holy Spirit, when he comes, will guide them into all truth (Rom 8:5, 14; Gal 5: 16-26). After Pentecost, one notices that Peter immediately understands Christ’s message and ministry and becomes empowered to preach effectively. In 1 Corinthians 2:12-16, Paul comforts believers by telling them that they have received the Holy Spirit, which he calls “the mind of Christ,” who is from God who teaches them and empowers them to understand God’s Word.
