That You May Believe | The Gospel of John || In the closing verses of John 7 we see it’s the last day of the Feast of Booths and Jesus cries 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.’” (John 7:37-38). It’s important we understand what took place on the last day of the Feast in order to more fully understand the significance of Christ’s invitation. On this final day, the priest would gather water from the pool of Siloam and bring it to the Temple where he would ultimately pour it out at the altar. This pouring out of the water both reminded them of God pouring out His blessing on them, as well as the promise that one day He would pour out His Spirit upon them. Christ, using this moment, reveals that it will be through Him this promise is fulfilled.
