Water represents life. Clean, fresh water is necessary for all living things to survive. But there's a difference between living and surviving. Surviving implies that you are barely getting by. Real living implies a fullness, satisfaction and contentment.
[Jesus said...] "Whoever believes in me, as Scripture has said, rivers of living water will flow from within them."
Jesus will fill you with hope, joy and peace to the point that it spills out onto others. Not because of who you are but because of who lives IN you.
May the God of hope fill you with all joy and peace as you trust in him, so that you may overflow with hope by the power of the Holy Spirit.
