John 7:37 On the last day of the feast, the great day, Jesus stood up and cried out, “If anyone thirsts, let him come to me and drink. Whoever believes in me, as the Scripture has said, Out of his heart will flow rivers of living water.’” Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified.
Psalms 143:6 I stretch out my hands to you; my soul thirsts for you like a parched land.
Psalms 63:1 O God, you are my God; earnestly I seek you; my soul thirsts for you; my flesh faints for you, as in a dry and weary land where there is no water.
Isaiah 12:3 With joy you will draw water from the wells of salvation.
Isaiah 44:3 For I will pour water on the thirsty land, and streams on the dry ground; I will pour my Spirit upon your offspring, and my blessing on your descendants.
Amos 8:11-13 “Behold, the days are coming,” declares the Lord GOD, “when I will send a famine on the land— not a famine of bread, nor a thirst for water, but of hearing the words of the LORD.
Revelation 21:6 And he said to me, “It is done! I am the Alpha and the Omega, the beginning and the end. To the thirsty I will give from the spring of the water of life without payment.
The celebration of the Feast of Tabernacles emphasized how God provided water to Israel in the wilderness on their way to Canaan. Jesus boldly called people to Himself to drink and satisfy their deepest thirst, their spiritual thirst. The invitation was broad because it said, if anyone. Intelligence, race, class, nationality, or political party don’t limit it. The invitation was narrow because it said, if anyone thirsts. One must see their need. Thirst is not anything in itself; it is a lack of something. It is an emptiness, a crying need. Jesus explained what He meant by the metaphor of drinking. To come to Jesus and to drink was essentially to put one’s faith into Him; to trust in, rely on, and cling to Jesus for both time and eternity. Jesus did not only speak of something coming into a person, but something flowing out of them as well. It was not only a blessing received, but also becoming a source of blessing to others. This outflowing life and abundance comes in and through the presence of the Spirit in the life of the believer. This speaks of an experience that belongs to those believing in Him. The nature of that experience may differ among believers, but there is some aspect of it that is promised to all who will receive it by faith.
