Hearing the Words. Walking the Walk.?

What non christian don't understand , when someone is born again , they are just a baby in Christ , and some never ever live anything like Christ . A christian believer is different from a true disciple , a true disciple puts Christ first , a believer ,can put himself first and not live anything like Christ and not be a good example and call himself a christian ,but is not a true spirit filled disciple , that is led by Christ . So you can have one extreme to the other , one that walk like Christ , which are few , and many that are believers that , walk after other things first and are not true ambadors for Christ , but still belivers and believers that should make it to heaven because God is a gracious God who does not want any to perish .
