Sermon B: Pentecost: John 7:37
The great festival of Pentecost will take place this year on June 4, 2006. The three readings are Ezekiel 37:1-14 (dry bones); Acts 2:22-36 (Peter's sermon) and John 7:37-39a (Receiving of the Spirit). The text chosen is John 7:37 which reads, "On the last day, that great day of the feast, Jesus stood and cried out, saying, 'If anyone thirsts, let him come to Me and drink.'"
The question before us is whether this verse is Law or Gospel. At first it sounds like Gospel in that all who come to Jesus will drink. However, one way to distinguish Law from Gospel is that the Law is a demand while the Gospel is a promise. Clearly there is no promise mentioned in verse 37. The promise is found in verse 38 that "out of his heart will flow rivers of living water."
Therefore, verse 37 is speaking to those who are thirsty and are invited to come to Jesus to drink. As we have already mentioned, theology is the art of making distinctions not only between Law and Gospel but also between the kinds of Law. Is verse 37 a kind of law or command that human beings are able to fulfill of their own free will? The only law that fits such a circumstance would be a command to be done in the temporal realm such as stopping at a stop sign, paying your taxes on time and the like.
However, in regard to spiritual commands, no human being has an innate ability to fulfill any such instruction. While it is true that it is the Law that is used to create thirst for salvation, the Law cannot motivate anyone to seek out Jesus in order to quench that thirst. The reason? Because prior to seeking out how to quench a thirst, one needs to know that what is taken will indeed quench that thirst.
For example, if after playing tennis a person is thirsty, they would not look for the nearest flower to eat to quench that thirst. Why? Because they would not believe that the flower is used to quench thirst. Instead, they believe that a liquid is necessary to quench thirst. The point is simple. Prior to using an item to quench thirst, there must be faith that the item will indeed quench that thirst.
Similarly, though the Law's accusations and demands make it clear that we are indeed thirsty for salvation, until we believe in Jesus as the One Who only can quench that thirst, we will never come to Him. Thus, faith always precedes action. Though the command is to come to Jesus, the ability to do so is only given by the Holy Spirit by creating faith in the heart of an unbeliever who now has become a believer.
That is why verse 39 is so critical to understand that the only ones who will have living water flowing out of their hearts (verse 38) are those who through the Holy Spirit have received the gift of believing in Him (verse 39). While the Law can make demands in both the temporal and spiritual realms, only with the Holy Spirit are the spiritual demands met as He creates a clean heart and renews a right spirit. God gets all the credit for our having been saved.
