I seem to get bullied a lot at school for being christian, I've tried ignoring them but it doesn't work, I've also tried being nice, but they just hurt me more.
WHAT DO I DO?
What exactly do you mean by "hurt me more"...?
Is this 'abuse' more than verbal?
Is it merely ["at the level of"] 'teasing' - or, is it more severe?
Is it just simply a matter of them "pinching you" and that sort of thing?
Or, is there "serious invading" of your body, "personal space", or personal property?
Is it boys or girls - or both?
How much of it is verbal? How much of it is physical? How much of it is "mind games"...?
If there is actually anything going on that is "prank-level" or worse -- is there anyone "in authority" (who is 'closer' to the situation) you can go to for advice or help?
Can you talk to your parents about it?
As for an answer to your question...
~ Keep them in your prayers.
But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; ~ Matthew 5:44
~ Give them an answer...
But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear: Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse your good conversation in Christ. ~ 1 Peter 3:15-16
Every time they come around, be sure to "drop" some scripture "into their ear"...
For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart. ~ Hebrews 4:12
This alone may "drive them away" - hearing scripture is worse than "fingernails across a chalkboard" to many whose heart is full of mischief...
~ Keep "being nice" to them...
Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. Be not overcome of evil, but overcome evil with good. ~ Romans 12:20-21
(Read the whole chapter.)
In other words - "be the instrument" that "surrounds them with godliness"...
Soon enough, they should either "cave in" (which is to their benefit) or "become scarce" (which is to your benefit).
I know these things can be difficult to do at times. Pray for wisdom to know "when and where and how" to "respond"...
I will pray for you...
