Whose purpose is it? Mine or Christ's? I believe that it was the purpose of the Gospel to save people for eternal life. And that is the purpose for which Christ suffered, died and rose again.
As I said before, to "His purpose".
Chewed gum is right in perspective here. The Gospel is the Good News of what Christ has done to redeem us to His purpose. Redemption without purpose is purposeless.
Point is, many Christians today are down-playing everything outside of soul-winning as unimportant and in doing so, clear themselves of the purpose for their life that God has for them.
I think the interesting question to Rick Warren or any Christian is, if Ashley Smith was not abducted by Brian Nichols, but had a choice, should she have chosen to risk her own safety to try to "reach" or persuad him. Most people would say no. i think God says yes- this is our purpose.
