John 7:37-39 : Now on the last and greatest day of the feast, Jesus stood and cried out, “If anyone is thirsty, let him come to me and drink! He who believes in me, as the Scripture has said, from within him will flow rivers of living water.” But he said this about the Spirit, which those believing in him were to receive. For the Holy Spirit was not yet given, because Jesus wasn’t yet glorified.
When the time was right, Jesus cried out to the people, offering an abundant life to anyone who was thirsty for Him. This is one of the most amazing descriptions of the Holy Spirit we have. He describes the work of the Holy Spirit as rivers of water flowing out from a person. He could have said that you will have a stream flowing out of your life. He could have said you will have one river flowing out of your life. Instead He said “rivers.” This is no small change for one who was once thirsty!
Have you ever wanted to make a difference in the lives of others or do something that would really benefit those around you? Jesus is in the business of changing a person from being a consumer of life, to being a mass producer of it. The Holy Spirit changes the economy of life in a big way.
Anyone, of any nation, without or without money, man or woman can have rivers of water flowing from within him (Galatians 3:28). This is the blessing of God that He has provided in Jesus to those who believe. Not only that, but God loves to take those who are weak, poor, talentless, without education, born in the wrong neighborhood, etc. to demonstrate His power. On top of that, He accepts sinners because He was about to make them capable of being legally forgiven.
1 Corinthians 1:26-29 : For you see your calling, brothers, that not many are wise according to the flesh, not many mighty, and not many noble; but God chose the foolish things of the world that he might put to shame those who are wise. God chose the weak things of the world, that he might put to shame the things that are strong; and God chose the lowly things of the world, and the things that are despised, and the things that are not, that he might bring to nothing the things that are: that no flesh should boast before God.
Because of this, Jesus could call out in a crowded place full of normal people and offer rivers of life to anyone who would accept it from Him.
