“For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.” Matthew 5:18.
“And it is easier for heaven and earth to pass, than one tittle of the law to fail.” Luke 16:17
The jot was the smallest letter of the Greek alphabet, and the tittle was even smaller, a piece of a letter. It would be easier for heaven and earth to pass away, Jesus said, than for one small part of a letter of the law to pass away.
God’s Law of Ten Commandments cannot be changed. Yet man has attempted it. The “little horn” power of Daniel 7 would “speak great words against the most High…and think to change times and laws….” Daniel 7:25.
And Satan would make special warfare against those who keep God’s Law, unchanged. “And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.” Revelation 12:17.
Sin first came into the world when Adam and Eve chose to disobey God. The Bible says that all sin can be defined as breaking the law. “Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.” 1 John 3:4. Because God’s Law had been broken, there was now a penalty. “For the wages of sin is death….” Romans 6:23. So that we would not have to die that eternal death, Jesus came to die and suffer the penalty of sin for us.
If God could have changed His Law, or altered its penalty in some way, Jesus would not have needed to come and die. He could have simply removed the Law and mankind would no longer have been guilty of breaking it, no longer have been under the death penalty. The very fact that God had to go to such a great length as sending His Son to die, shows that the Law could not be changed.
