Pity and Promise
The most engaging and exhilarating contemplation for the Christian mind is the mystery of the great Three-in- One. A mystery, not in the allegation that it does not make sense, but in the fact that the three-ness or plurality of God can only be known by revelation - his own self-disclosure.
The reality of the Triunity of God is a matter of enabled spiritual observation, not of human discernment or acumen or impossible mathematical juggling. The One Lord manifests himself as Three: Father, Son, and Holy Spirit. Throughout the history of his Word, spoken to mankind via prophets, apostles and chosen witnesses, divine speech proclaims God as being internally, essentially, and by nature, a society of three members of the One Godhead, one Being diversified in three personal entities in harmonious communion, will, and action.
