I think we should pay attention to it but our main focus should be on God himself,this is not to say that we cannot have a good deal of focus on it I myself study the end times out of interest not really because I am trying to figure out when it all goes down or how it all goes down. but I do think God wants us to not be ignorant of the prophetic happenings and to look for and recognize the signs. though more often than not it's not that people aren't looking for the signs it's that they are looking for them and see what they want to see not what God is really showing.
