Can My Life Really Be A Witness For God?
So often, when I look back over my life; I see all the times that I have failed to love God as I should. I see my failures looming like giants and God’s grace as greater still. The other day I heard from someone out of my distant past, who said; “Because of you, I found Christ. You had such a tremendous impact on my life.” Now, what is more amazing, when I remember that time in my life; I realized that it was God’s Grace that allowed them to see Christ through whatever blurred picture I was displaying. Truly, I remember a bumbling, faltering testimony. A candle that barely flickered and a stream that had so little water trickling through it. Through the scars, cracks and crevices of my life the Holy Spirit shone forth and had touched another’s soul. That for me is such a humbling thought; that God would be so gracious as to use someone like me to do His work. So, if you ever thought that you are a poor witness for Christ or ever worried that your testimony would be more of a disgrace than benefit to God? God has promised to be the rivers of life flowing through your heart and mine for others to see His Glory and come to Christ. Why do I say that? 
JESUS PROMISE TO OVERFLOW OUR HEARTS WITH LIVING WATER
Remember that where we left off on Monday, Jesus had quietly gone up to the feast of the tabernacles and had been teaching in the synagogue every day. “37 On the last day, that great day of the feast, Jesus stood and cried out, saying, ‘If anyone thirsts, let him come to Me and drink. 38 He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water.’ 39 But this He spoke concerning the Spirit” (John 7 NKJV). Up until now in the book of John we have heard that Jesus has said that He is the living water, He is the bread of life and that He brings spiritual birth. He has presented this through His words and through the example of His miracles from changing the purifying water into wine to feeding the crowd. Now He takes this one step further by saying, “Not only will I be life to all who believe in me; but, I will fill them to the overflowing so they can spill over rivers of life to others.”
