37 On the last day, the climax of the festival, Jesus stood and shouted to the crowds, “Anyone who is thirsty may come to me! 38 Anyone who believes in me may come and drink! For the Scriptures declare, ‘Rivers of living water will flow from his heart.’” 39 (When he said “living water,” he was speaking of the Spirit, who would be given to everyone believing in him. But the Spirit had not yet been given, because Jesus had not yet entered into his glory.)
When you are truly saved and know Jesus Christ as Savior and Lord, you will certainly know it. That is when the Holy Spirit of God comes to live within you and your joy and excitement about following Jesus will flow from you like a river of water. That is what Jesus meant in the verses above. You can't help but talk about the change He has made in your life.
Yes, there are times of difficulty and stress in our walk with Him, but there are far more times when our life in Him will flow to all that surround us. If you haven't yet, why not taste the living water today?
