Perpetuity of the Law of God

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. Matthew5:18

"The first is that the law of God is perpetual: “Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law.'' 

The meaning is that even in the least point it must abide till all be fulfilled. 

Secondly, we perceive that the law must be fulfilled: Not “one jot or one tittle shall pass from the law, till all be fulfilled.’' 

He who came to bring in the gospel dispensation here asserts that He has not come to destroy the law, but to fulfil it.

The relationship of the law to myself, 

and how it condemns me: 

the relationship of the gospel to myself, 

and how if I be a believer it justifies me— 

these are two points which every Christian man should clearly understand.

Not long ago there were those about us who affirmed that the law is

utterly abrogated and abolished, and they openly taught that believers were not bound to make the moral law the rule of their lives. What would have been sin in other men they counted to be no sin in themselves. From such Antinomianism as that may God deliver us. We are not under the law as the method of salvation, but we delight to see the law in the hand of Christ, and desire to obey the Lord in all things.

How very unlike to those which the apostle used when he said, “The law is holy, and the commandment holy, and just, and good.” How different from the reverent spirit which made him say,— “I delight in the law of God after the inward man.” You know how David loved the law of God, and sang its praises all through the longest of the Psalms. The heart of every real Christian is most reverent towards the law of the Lord.

A sanctification which stops short of perfect conformity to the law cannot truthfully be called perfect sanctification, for every want of exact conformity to the perfect law is sin." 

Charles Spurgeon
