Are You a Christian? Am I a Christian? Is She a Christian? How About Him?

"The Kingdom of Heaven is like treasure hidden in a field, which a man found and covered up. Then in his joy he goes and sells all that he has and buys that field. Again, the kingdom of heaven is like a merchant in search of fine pearls, who on finding one pearl of great value, went and sold all that he had and bought it."
-Matthew 13:44-46

The other day in a late night/early morning chat with some friends the question, "How do we know if people are truly Christians?" came up. Honestly I know that we frequently ask this question looking at others, and sometimes even looking at ourselves. I think Jesus did a pretty good job at showing us how not only through His life but also through His words, especially the ones quoted above.
You see I fully believe and know that we know when someone is a truly a Christian when one two one thing happens;
Upon discovering the mystery and wonder of the Gospel, they go completely head long into it and eat up anything and everything they can about God, scripture and being His child. That they will spiritually, emotionally, and sometimes physically give everything away and up only to desire and seek Him better and more.
You see I think a lot of times we over think Christianity, we make lists and regulations, requirements and duties. This is why I know people shun the Christian faith because in our foolishness to seek Him better we have really done the opposite and counter acted the very words of Jesus.
I fully believe that in this we as the western Church have become a pharisaic faith. Now I am no it going to start bashing on the church, I love church, there is a reason why every Sunday I get up and go to it. But what I am saying here is this, Christianity is simply, but we make it hard, really really hard.
We look at someone and we say, "Okay so if you want to be a Christian you need to; Go to church every Sunday, make sure you or your kids also go to youth group on Friday, Bible reading must be a daily thing, prayer is important so make sure 15 minutes of your day is spent in it. Make sure you read books on faith, such as Francis Chan, C.S. Lewis, oh and listen to David Platt, he is really good. You can't swear, you can't drink, you need to be careful what you listen too, and what you watch, well just to play it safe, always listen to worship music, like Kari Jobe, Micheal W. Smith, and Hillsong, Hillsong is really good, also if you don't like David Crowder and you are a hipster you are clearly not a Christian Hipster (For the sake of being honest I actually can't stand David Crowder, personal preference). On Sundays you have to wear a tie if your a guy and do your hair if you are a girl, jeans.... jeans in the church are not aloud, hats as well, and anything that doesn't really look like you aren't going to a wedding or a funeral"... and so much more
You see what I mean though, you know what Jesus said about being a Christian?
Now this is me paraphrasing so I apologize for my Message like wording here,
"To be a Christian, really all it means is once you find me, you realize how fake everything else is, and how it will never please you like I fully do. So you drop it all and completely desire and follow me." Not "You need to do this, you can't do this."
Jesus Simply wants us to desire Him with our whole life, and as a result of that desire our life then doesn't need anything else, doesn't think of anything else, doesn't find full pleasure, full fulfillment, full completeness and full peace in anything else but Him.
So how will people know we are Christians, how will you know yourself that you are a Christian? Because nothing else satisfies but Him and that is so clear because we drop everything for Him. Our desire is so strong that no matter what happens in life we have a strange sense of peace, that sure our money might be in the negatives, the struggle might be real, we might have no friends, we might be bullied for what we believe in, and so on, but in all of that our faith, trust, reliance and passion for Him only continues to grow in it.
"They will know we are Christians by our love, by our love" for Him.
