Jesus wants us to be perfect as our Heavenly Father is perfect and to think as God does. Apparently, he thinks highly of us, his creation. How do we regard ourselves? We can feel sorry for or even hate ourselves, we can brush aside God and go on our own way, we can halfheartedly follow him ... all these options are wrong because they disappoint God by ignoring the potential he sees in us. As a matter of fact, it is sinful to not believe that God can transform us. We should thank the Lord for wanting to make us holy so that we may enter union with him and be joyful forever from this life on. Therefore, think about not yourself, but what God thinks of you.
