God Prophesies He Will Destroy Egypt

Today I read Ezekiel 30 where the Lord tells Ezekiel that He will use Babylon to destroy Egypt.  I suppose this might be welcome news if the Israelites did not like the Egyptians, but as I recall they were kind of ambivalent towards them.  I'm honestly not sure why the Lord made a point of telling the prophets that He was going to do this, unless it was just to prove that He was God, which is always important.  In order to have faith in God, we have to know that He is God and that we can trust Him.  We have to know that He will follow through on what He says He will do.  We have to have a correct understanding of His character.  Perhaps that is what this prophecy is all about.  I'll just have to ask God one day to find out for sure.  Until tomorrow.
