Some people haven’t received everlasting life as a gift of God from this well of water because:

They don’t know the gift of God.  Jn 4:10 “If thou KNEWEST the gift of God”.  They don’t know what the gift is. It’s eternal life, v.14.  It is the answer to sin and death.  God is an eternal being.  Only he can give eternal life.

They don’t realize that this is the GIFT of God, not some religious pursuit or journey.  It’s not some achievement award.  It’s a gift.  This gift is not of works lest any man should boast, Eph 2:8-9.

They don’t realize that this is a gift OF GOD.  This is not a man made religious idea.  Or some manufactured spiritual concept.  God so loved the world…, Jn 3:16.  See Rom 6:23.

They don’t know the giver of the gift of God.  “And who it is that saith to thee”.  They don’t know Jesus Christ.  They may know something about him.  But they don’t know him, anymore than this woman knew him.  But as he made himself known to her, v. 25-26, he will make himself known to you, IF you want to know him.  She knew that he was the Christ.

They don’t know how to obtain the gift of God.  “Thou wouldest have asked of him”.  They haven’t asked him.  Either because they have’t been told or they have been told incorrectly or they don’t want him or they don’t believe.  You should ask him like this woman did, v.15.  As he asked for a drink from her well, so she asked for a drink from his.

They don’t know he will give them the gift of God.  “He would have given thee living water”.  He’ll give it to anyone who will ask and believe.  This woman was certainly no saint, v.16-18.  He died for sinners.  Yet, he gave her the gift, v.29.

She understood that the living water he was offering was not physical water but spiritual.  Jesus said in v.13, “Whosoever drinketh of this water shall thirst again”.  True.  Jesus had come to this well to get a drink of water, v.6-7.  Obviously, Jesus had thirsted for physical water.  He even said on the cross, “I thirst”.  So, he is talking about a thirst for something spiritual.

He said, “Whosoever drinketh of the water that I shall give him shall never thirst”, v.14.  Matt 5:6 says, “Blessed are they which do hunger and thirst after righteousness: for they shall be filled”.  In Jn 6:36 Jesus said, “He that believeth on me shall never thirst”.  He’s talking about quenching a thirst for God.  David wrote, “O God, thou art my God; early will I seek thee: my soul thirsteth for thee, my flesh longeth for thee in a dry and thirsty land where no water is”, Ps 63:1.

How are they going to find out?  Jesus told her to “Go, call thy husband, and come hither”, v.16.  When she found out that he was the Messiah and believed on him, she “left her waterpot, and went her way into the city, and saith to the men, Come, see a man, which told me all things that ever I did: is not this the Christ”?, v.28-29.

Finding the Messiah completely changed the course of her life.  She had come to the well to get some water in her waterpot.  But when she found the Messiah, she left her waterpot.  Temporal matters become less important than eternal matters when Jesus enters your life.

Those who have drunk of the living water tell those who are thirsty where they can find this water.  When we have the gift of God, we have drunk of a well of water.  This is not a stagnant pond, this is a flowing river, Jn 7:38.  It goes from us to others.

This is a well of water springing up into everlasting life.  Your well needs to flow to others.  This is exactly what the woman did in v.39-42.

Conclusion: If you have not drunk of this water will you believe on Jesus today and take a drink of the living water in the well of everlasting life?

If you have drunk of this water, will you tell someone else about Jesus Christ so that they can have a drink of everlasting life?
