Every human being has a need related to his or her condition. In his Gospel, John uses nine cases to represent the various conditions and needs of human beings in order to illustrate that Jesus Christ as life fully meets the need of man’s every case. In this booklet taken from Life-study of John, Witness Lee considers further the sixth of these nine cases, which illustrates the need of the thirsty. This booklet centers around John 7:37: “Now on the last day, the great day of the feast, Jesus stood and cried out, saying, If anyone thirsts, let him come to Me and drink.” Everything has its last day. Every feast comes to an end, and we will feel thirsty. Then we must come to the Lord Jesus and answer His cry. To have our thirst quenched, we must come to Him and drink of the living water.
