He said to them, “So then, every Torah-teacher who has been made into a talmid for the Kingdom of Heaven is like the owner of a home who brings out of his storage room both new things and old.”Mat 13:52
Every teacher, writer, scribe or secretary that has taken grasp of the Kingdom of God spreads from his storage room, his treasure, the wealth that God provided in him by means of the gift deposited in him both trusted and well known doctrine as much as revelatory prophetic new insight into the Word of God. And he does that in season and out of season.
A scribe started to be taught in his profession in Israel of old at the age of 14 and finished his apprenticeship at the age of 40. They were responsible for new copies of the biblical scrolls and well able to teach the law. As it was most important when copying the Bible not to change a Yota, they at the time of Jesus as we know tended to follow the letter of the law more then its spirit.
I personally started my Bible studies when I entered boarding home at the age of 14 and 4 months. We were allowed to read the Bible during study hours (2.5 hours daily) after having done our home work. So I read a lot.
With 40 years and 4 months I joined my church, knowing that I had been placed where God wanted me to be. All up to this point was preparatory.
Growing into the call and office of a teacher, I’m searching the Lord so I can from the treasure he provided me pass out the new and the old.
I recommend the book by Mark Stibbe, “The Teacher’s Notebook“, on the subject for everybody that either is called to be a teacher in the body of Christ or has to work together with them.
