سوال: فکر می کنید چقدر به هدف هایتان از ساخت این سریال رسیدید؟
در حد کتاب خدا به قط و یقین نه ! ولی در حد توانمان رسیده. یعنی من توانم اینقدر نبود که در تمام کره زمین تاثیر بگذارم. کشوری در دنیا نیست که یوسف را ندیده باشد و یا در حال دیدن نباشد. این توان در حد ما نیست و مطمئناً دستی وجود دارد که به ما کمک کرد، چون ما میزان توان خودمان را می دانیم. البته ضعف هایی هم وجود دارد، اما در مجموع این را می گویم که آن چیزی که اتفاق افتاد 300 درصد آن چیزی بود که انتظار داشتیم.
Best wishes, and many thanks,

Discussion
You are right. we can say here: To reach to the standasds of God's Book or according to the standards of the Book.
Isn't the idea here that of what we are measured by? When we measure ourselves according to God's standards (God being the ultimate author of all holy books) we always fail utterly, but when we measure ourselves according to our own powers and gifting, that is another matter.
