This may sound weird to you but I quit being a "Christian" when I learned I was His child.
As His child, I have a more intimate relationship with Him. As my Abba/Father, He has a responsibility to me to teach me His ways.
For me, and this is just my humble opinion, the word christian has lost it's integrity of what it is suppose to represent....(slaves to Christ is the original meaning)....which implies to be like Jesus.
When you say you're a christian, in the mindset of the world these days it says to them that you are hypocrit that preaches it but doesn't practice it.
How sad....
