Perfect Practice makes Perfect

I am in my high school's band program.  All summer we heard it's not just any kind of practice that makes perfect.  If the way I practice my music is not up to my teachers standards then I will get in trouble.  How you practice is how you will become.  This is a lot like being a Christian.  As Christians we have to prepare for the day Jesus will return.  So how are we supposed to prepare? A few ways to prepare for this is to attend church service every time the doors are open, read and study your Bible, and you could attend devotionals.  Just like during the summer when I was preparing for football games not all the ways you prepare are good.  If you put your self in bad situations then what do you expect.  You might not think that they do but the people around you have an influence on you, so surround yourself with good christian people.   Don't be a hypocrite.  Practice what you preach.
