It is so good, I wish I was the one who wrote it. It blew me away.
I can tell you what church certain people belong to just by the way they comb their hair or the dress code they abide by.
It is also pretty easy to tell what persuasion of theology church goers are associated with just by the phrases they parrot. They simply repeat the same phrases and sound-bites they have been taught (or read somewhere) – it’s a special insiders language of code words that reveals they are in the club. Now, you couldn’t learn this stuff from the Bible itself – you have to be taught it by men, who then attempt to use the Bible to prove their presuppositions. Just listen to them and you’ll hear the same phrases regurgitated over and over again. These disciples are simply the parrots of men. It’s really pretty pathetic.
Parroting the learned phrases of men does not prove the authenticity of ones Christianity. It only demonstrates they are faking it.
You see, God does not want you pretending to be somebody that you are not. You are unique and He wants you to be the person He has wired you to be. Simply allow Christ to be formed in you on a daily basis.
That's what it means to be authentic, and this kind of testimony is a lot more convincing too.
