I hear it a lot in the City of London. I see it a lot, too. Some say that it's all to do with confidence, a form of therapy to assist you in getting on in life. Act like you belong - or like you have some ability that you don’t - and eventually you will figure it out, the doors will open. An example of a positive feedback loop.
But isn't it all about being someone that you are not? Putting on a mask, trying to project an image of someone who you want to become, but aren't ... yet. Are you lying to the world - or lying to yourself?
I don't want to be 'fake'. I want to be myself - whole, complete, the person I am intended to be by God. Which is not necessarily who I want to be - it's who God wants me to be. Listen to this:
Galatians 6:3 (NIV)
If anyone thinks they are something when they are not, they deceive themselves.
I don't want to be 'fake'. I want to embrace who my Father in Heaven has made me to be. To be true to myself.
And so, that's more to do with 'faith' than being 'fake'.
It's about trusting God when things aren't going the way you want them to - not covering up and pretending that all is well.
And that's when it comes down to you and God.
If God has called you to do something, you need to be faithful in that. Be faithful in the small things that are open to you. Trust Him. Give Him everything that you've got and eventually you will make it to the next level; a door will open.
