This has improved with new technology, but the quality level goes down when you make a copy of a copy. With every copy of a copy, of a copy, the quality diminishes a little more with each reproduction. You should copy only from an original printout to ensure the highest resolution. 

I think this is true for disciples, too. Jesus could say, follow me or imitate me. The Apostle Paul could say imitate me as I imitate Jesus. But that does not mean that you or I should have people imitate us, too. 

To be the best version of a Christ follower, you should try to imitate Jesus or Paul, not anyone else. I know I am not a person whose life you should copy. I have so many flaws and failures. Every Christian I know is the same way, and I know some great people of faith. 

We must be careful about what we copy from others. A flaw in someone you admire can become a significant issue for you and will definitely be one for someone who tries to imitate you.

I am glad you have someone discipling you, but always compare their life to Jesus. Just because a friend thinks they are spiritually mature does not mean they are living like Jesus in every way.
