This is such a beautiful and poetic metaphor for our relationship with God. Reading this I wonder if Ezekiel was tempted to dive under the water, let it surround him, then take a deep breath. I wonder then, if the water would have flooded Ezekiel's lungs would give him life, instead of taking it.
Many times our faith seems just as contradictory as this. We need to fight against our instincts to do the right thing. I fight against my sinful instincts - those times when I don't want to show grace or patience; those times when no one is looking - take a deep breath, and and allow God to breath living water into my very being.
That's what the resurrection did. The cross was a moment in time, but the resurrection is renewed each day! So dive deep into those living waters, knowing that the source is the risen Saviour - your creator.
