Christianity is only out dated because nobody wants to follow Christ...
But thats the same with all religions i guess... If muslims were commited to living the koran, or people listened to Ghandi then the world would be a completely different place. But its easy to say your something but not live like you are.
In my opinion, christians today have become lazy. Some people get into the mind frame that they are saved no matter what they do, which is true, but you cant show someone you love them if you dont put effort into the relationship.
For so long it seems we've lacked the motivation to live christianity, and because of that noone knows what christianity is... We're just a bunch of nay sayers pointing our fingers at anything we personally dont agree with saying "God doesnt want you to do this, He certainly doesnt like that"... God already gave his opinion on what he wants and we'd be better off to listen to it!
Genesis 2:24 said:
For this reason a man will leave his father and mother and be united to his wife, and they will become one flesh.
By this definition, the very moment you have sex with someone you are married to them. Not when you go through some fancy ceremony. So technically you cant have sex before marriage. But that also means if you have sex with one person, then go and have sex with another, you are breaking the terms of marriage. And as Malachi 2:16 starts:
"I hate divorce," says the LORD God of Israel
Showing thats not what God wants.
And shown again by Jesus:
Matthew 5:27-28 said:
"You have heard that it was said, 'Do not commit adultery.' But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.
The commitment i am called to is to have a sexual love one person and one person only. The one i have sex with is my wife, and if I desire another woman, then I'm not living how I am called to live. I dont care if people feel sorry for me because I know that the person I do love gets ALL my love. Everything I have to offer is hers
That doesnt mean Im perfect... far from it. But God's grace is like a safety net to catch me when I fall. It would be stupid for a tight rope walker to never leave the saftey net because they are probably going to fall. So its stupid for me to live relying completely on grace to get me through. Although it will do that, thats not what its there for.
If you're are thinking that this is stupid because you should experience other people before you settle down, then you go do that. Only christians are bound by the guidelines that Christ told us to live by. I can't force the values of what I believe onto someone who doesnt believe it.
All I can do is put effort into living the life I am called to live. I am convinced of what i believe, and I know that christianity is relevant today... if only christians would live it
