The personality of the Godhead may come forth most explicitly at Jesus’ baptism2. There we see the Father in heaven, the Son manifested in the flesh on earth, and the Holy Spirit anointing the Son like a dove. We also find statements about specific attributes of the personality of the Godhead with Jesus and the apostles in the upper room10 and in Peter’s opening6 and Paul’s closing5 of their epistles.
Maybe most poignant for the Christian today are the roles that the Godhead fulfills in the redemption of man3,4,7,8,11,14,15,16,17. What might be best summarized by Jesus when He confounded the leaders in the temple15, we also find discreet participation by each personage in sanctification3,7,8, selection6,7, fellowship5,11, suffering16, and love5,17. The Christian, by his/her obedience6 to the Son’s word8,15 and subsequent adoption as sons9,16, is established by the Father4, anointed by the Son’s blood4,6 in baptism3,13,14, and sealed/set apart in/by the Spirit3,4,6,7,8 for glory7,16 and membership in God’s household11, the unified12 church!
