" The Gospel of John was written at least twenty years after the last of Paul’s writings. Since John’s ministry was a mending ministry, his Gospel is a mending Gospel. Problems had been caused by certain ones who called themselves Christians but did not believe in the deity of Christ. In his Gospel John mended the damage caused by this lack of faith in Christ’s deity. His Gospel reveals clearly that Christ is God. Furthermore, we have pointed out that in the very Gospel which emphasizes the deity of Christ the eating and drinking of the Lord are also emphasized. We have also seen that in the book of Revelation we find reference to both eating and drinking. This indicates definitely that John’s ministry, like that of Paul, stresses the importance of eating and drinking the Lord. Without eating and drinking, there is no way for us to be proper Christians. It is of vital importance that we learn how to drink the living water. There is the need to give our attention to all that the Bible reveals concerning how to drink the Lord. "
