Paul said in 1 Cor 11:1 Imitate me, as I Imitate Christ.
I can’t teach people until after I show them. My example should be such, that I can confidently encourage people to become like me, as they progress towards becoming like Christ. I must recognize “becoming like me”, as a genuine stage in becoming like Christ. This puts some very healthy pressure upon me to actually live a sound Christian life.
My example either validates or nulifies everything I say.
