As I was reading Preach My Gospel tonight, I came to this quote by Elder Dallin H. Oaks. Very powerful statement!
"We do not preach and teach in order to 'bring people into the Church' or to increase the membership of the Church. We do not preach and teach just to persuade people to live better lives...We invite all to come unto Christ by repentance and baptism and confirmation in order to open the doors of the Celestial Kingdom to the sons and daughters of God. No one else can do this."
