On the last day of the feast, the greatest day, Jesus stood up and shouted out, “If anyone is thirsty, let him come to me, and let the one who believes in me drink. Just as the scripture says, ‘From within him will flow rivers of living water.’” (John 7:37)

We have, lastly, in these verses, a promise held out. The Lord Jesus says, “He that believes on me, from within him will flow rivers of living water.” These words of course were meant to have a figurative sense. They have a double application. They teach, for one thing, that all who come to Christ by faith shall find in Him abundant satisfaction. They teach, for another thing, that believers shall not only have enough for the needs of their own souls, but shall also become fountains of blessings to others.

The fulfillment of the first part of the promise could be testified by thousands of living Christians in the present day. They would say, if their evidence could be collected, that when they came to Christ by faith, they found in Him more than they expected. They have tasted peace, and hope, and comfort, since they first believed, which, with all their doubts and fears, they would not exchange for anything in this world. They have found grace according to their need, and strength according to their days. In themselves and their own hearts they have often been disappointed; but they have never been disappointed in Christ.

The fulfillment of the other half of the promise will never be fully known until the judgment-day. That day alone shall reveal the amount of good that every believer is made the instrument of doing to others, from the very day of his conversion. Some do good while they live, by their tongues; like the Apostles and first preachers of the Gospel. Some do good when they are dying; like Stephen and the penitent thief, and our own martyred Reformers at the stake. Some do good long after they are dead, by their writings; like Baxter and Bunyan and M’Cheyne. But in one way or another, probably, almost all believers will be found to have been fountains of blessings. By word or by deed, by precept or by example, directly or indirectly, they are always leaving their marks on others. They know it not now; but they will find at last that it is true. Christ’s saying shall be fulfilled.

Do we ourselves know anything of “coming to Christ?” This is the question that should arise in our hearts as we leave this passage. The worst of all states of soul is to be without feeling or concern about eternity–to be without “thirst.” The greatest of all mistakes is to try to find relief in any other way than the one before us–the way of simply “coming to Christ.” It is one thing to come to Christ’s Church, Christ’s ministers, and Christ’s ordinances. It is quite another thing to come to Christ Himself. Happy is he who not only knows these things, but acts upon them!
