Standing for Christ is a hard thing to do because of rejection. People will ridicule and tease you for being a Christian. It still happens to me. And my classmates have known for a while kno. Don't be afraid of rejection. People will reject you at least once in your life so don't let it bring you down. People will get used to it. I normally put signs on my school locker obout Christ or Christ like slogans. I even wore a shirt one time that said, "JESUS IS THE LIGHT" with the TWILIGHT© font! man did people get angry. They loved twilight more than God! isn't that sad! (personally i don't like twilight to much.) But be bold! Speak out! and don't be afraid! man, i wish i could count how many times the Bible says do not fear! Also it good to witness to lost classmates. they may come to Christ or they might think you are wacko and try to question your faith. it's always good to know how to defend it. try reading books by ray comfort. he's a great evengelical. but be bold and don't be afraid of rejection!
