just some questions i have...

i guess they sorta of all tie in together...but here are my questions...one in verse 9 chapter 2....verse 11 of chapter 2 too......so u can't be a Christian if u hate ur brother......so then who is ur brother......jsut other christians.......okay new verse......verse 6 of chapter 3 and also verse 9 of chapter 3........so if you continue to sin or maybe messes up doesn't know Jesus..........verse 15 of chapter 3.........so again it goes to say if u hate ur brother you are a murder and no murder has eternal life.......so by be just hateing tha couple guys means i won't have eternal life..........so again is this jsut like brothers that are Christians as well or any person.........okay now verse 8 of chapter 4.........it says if you do not love then you do not know God.........verse 20 chapter 4..........i THINK i do love God......but now i don't know......because there are still at least a couple of people i hate.........i don't know.......i think i'm a Christian but these veses are a litle confusing to me......i read all surounding verse around them.....but still am confused.......i really don't know........in a way these verse scare me.............i want to love God........but don't know if i really do.......i guess in a way it goes back to Love God/Love people..........But i don't know......so if i just hate someone means i'm not a Christian and don't love God..........grrrrrrrrrrrrrrrrrrr...............and one other question.......is it possible to love others but not love yourself......cause the bible says love your neighbor as ur self......but if you don't love yourself and hate urself can u still love others..........oaky that's all i have for now...........
