“Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill. 18 For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled. 19 Whoever therefore breaks one of the least of these commandments, and teaches men so, shall be called least in the kingdom of heaven; but whoever does and teaches them, he shall be called great in the kingdom of heaven"
Matthew 5
"But beyond this, my son, be warned: the writing of many books is endless, and excessive devotion to books is wearying to the body.
The conclusion, when all has been heard, is: FEAR GOD AND KEEP HIS COMMANDMENTS, because this applies to every person. For God will bring every act to judgment, everything which is hidden, whether it is good or evil."
Ecc 12:12-14, New American Standard Bible
