David speaks of visiting the earth with water. We may have a problem about that today because in our land today some parts are flooded and some are in severe drought, but without water we would cease to exist. David speaks of rain as a visit from God. The flood in Noah's time was definitely a visit from God. Not because of their goodness but because of their evil ways. I really don't know how to end this except that we must praise God for His goodness no matter what comes our way.
