so what i was wondering, is it wrong to base my thoughts and opinions on christianty on purpouse driven life rather than the bible?
To put it plainly, the answer yes, it is wrong. The Purpose Driven Life (while a helpful book) cannot replace the Word of God.
To begin with, the bible is the inspired, infallible Word of God. The Purpose Driven Life was written by man; quite possibly it was inspired, but it is not infallible. There are passages taken from many different bible versions - taken, in fact to fit with Rick Warren's views - which somewhat change the meaning of the verse.
I have been through the Purpose Driven Life twice - the first time was extremely helpful - it pushed me to dig deeper into my own faith and what I was doing about it. The second time when we tried to "go deeper" with the book and use the bible as a "check" the flaws began to appear.
It may be a useful tool to "jump start" your desire to grow in the Lord, but please, please don't use it as a replacement to the Bible. The Word of God is "sharper than a two edged sword" - it is where the truth will be found.
In Christ
