How can a Christian reject part of the Bible and still call themselves a Christian?

[Drich]

I had a conversation with Christian girl yesterday and it randomly led to the subject of homosexuality.
She believes that it is perfectly acceptable to be a homosexual because you should be able to love anyone you want.
I asked her how she could say that and call herself a Christian. She became iritated. I pointed out that her Bible clearly states that it is an abomination. She finally said " I don't care what it says" and ended the conversation. The stress caused by the cognitive dissonance was pretty high.
I find Christians do this a lot. They reject what they don't like in the Bible.

Here's the thing..

We/Christians don't get to call ourselves Christian and it mean anything.

:Mat 7:21
"Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven.

Christ goes on to compile a list of great things some of the self proclaimed christians have done... Saint/Pope level stuff. And yet they wrongly identify as Christian.

Christ is the only who can give us this lable, Christ is the only one who can save us. anything else offered/ever offered by a church or any religion is just lip service.

In truth we are not Christians/Not saved till we pass through judgement.. When ever the bible talks about salvation it is always point to the future "you shall be saved" you will be saved... not do this say this prayer and you are saved... not a thing. or not a bible thing, but it is a religion thing...

So you ask how can a christian do...

Here's Jesus' own words:
21 “Not everyone who calls me Lord will enter God’s kingdom. The only people who will enter are those who do what my Father in heaven wants. 22 On that last Day many will call me Lord. They will say, ‘Lord, Lord, by the power of your name we spoke for God. And by your name we forced out demons and did many miracles.’ 23 Then I will tell those people clearly, ‘Get away from me, you people who do wrong. I never knew you.’

So again we see people aligning themselves with Christ and his name, but did evil in their hearts, and he said away from me i never knew you/You were never a christian...

Now before you 'no true scotsman' on me know no true scots refers to arbutary rules to being a scot, verse actual rules conditions set fourth by Christ to being 'christian.'
