…but whoever drinks of the water that I will give him shall never thirst; but the water that I will give him will become in him a well of water springing up to eternal life.
For all who are in Christ they now have within them a well of water from which they can draw from anytime, the Holy Spirit. If you had a natural well of water but never made the effort to draw water up from that well you would become weary. So also do many Christians become weary for they either have never placed their faith in God to be baptized in the Holy Spirit with the evidence of speaking in tongues (a heavenly language), or once they have they do not daily draw from that well by praying in this heavenly language.
Many who are born again have not had this separate experience apart from salvation of being baptized (immersed) in the Holy Spirit with the evidence of speaking in this new heavenly language, which scripture reveals is a promise for all. In Jude 1:20 we are told that we build ourselves up on our most holy faith when we pray in the Holy Spirit. When you pray in this heavenly language you are drawing water from the well and therefore you will not become weary.
This is why the devil has brought so much deception in the area of the baptism of the Holy Spirit because he wants you to grow weary. If you have not been baptized in the Holy Spirit just ask the Lord in faith. Once you have been baptized in the Holy Spirit, then draw from that well every day from which you can receive refreshing by praying in your heavenly language, and you can experience rivers of living water.
