If rivers of living water flow from within you, surely it will touch many whom you meet daily. You will make a difference in the lives of many and it will be a difference for the good. Though you may not realize it, the Spirit of God who lives within you will touch them whom you deal with.
Perhaps he may bring them to a realization of their sinful life and the need of a Savior; perhaps he may flow in to their lives with a word of encouragement from you. The Spirit will flow as he pleases and achieve God's divine purposes.
So be a channel for the Spirit of God to flow through, each day that you live. That will bring glory to God the Father and to our Savior Jesus Christ.
