Three Gods, or One, or Three-in-One? Since the word Trinity does not appear in the Bible, many people wonder whether the doctrine is anything more than an intellectual puzzle created by theologians. This book takes readers on a guided tour of the logic leading to understanding God as a Trinity. The Father, the Son, and the Holy Spirit in the Bible (and in Christian experience) are all vital to the reality of salvation. All three save. This point may not seem to be very significant until seen in the light of the basic premise of the entire Bible, namely, that only God can save (Hosea 13:4). There are benefits involved in understanding God as a communion of persons, a circle of love. God is no longer viewed as a distant judge removed from the sorrows of earthly existence. Salvation can be seen as more than mere forgiveness of sins. It also involves a life-transforming communion of divine love. A robust understanding of the Trinity fosters a more full and transformed Christian life.
