whats going to happen at the end?

my church has been talking alot about the end of the world this summer and it has really gotten me to think about it. at first i felt really overwhelmed with it all. i mean an increase in wars, plagues, famines, violent storms and persecution - who wants that? its so easy to live in our easy lives and love Jesus and not think about times getting more difficult. but at some point Jesus is coming back for us and things will get rough. so after much prayer and thought i have decided i want to be ready. i want to know God's word so well that i can not be deceived. i want to love Jesus more than anything so i can stand up for Him no matter what.
