Jesus ministered in the power of the Holy Spirit (Luke 4:14) and promised to give the Spirit to His disciples (John 16:7). The promised gift of the Holy Spirit was fulfilled on the day of Pentecost (Acts 2:1). All believers are ‘indwelt by the Holy Spirit’ (1 Corinthians 3; Ephesians 1:13). The Spirit convicts (John 16:8–11), renews (John 3; 1 Corinthians 2:14), illuminates (John 14:25), transforms (Galatians 5), gifts (1 Corinthians 12) and empowers us for lives of worship (John 14).
