Jesus Returning

So in the bible right before Jesus is crucified (and rises from the dead) in the book of Luke he talks of the end of times. I was just reading this and he was talking about how the earth will change, like the seas, etc. And what stood out in my mind is just earlier I had bought a national geographic and the picture on the cover is of seas and the story under that is sea levels rising. So if the sea levels are rising throughout the world this has to be a sign. Not to mention all the violence that has been going on. It is true Jesus second coming is near, no one knows when, because only God knows the bible says, but this goes to show us that we all need to be ready at any moment for the returning of Christ so we can all go to Heaven to meet our Saviour.
