βThou shalt not remove thy neighbourβs landmark, which they of old time have set in thine inheritance, which thou shalt inherit in the land that the Lord thy God giveth thee to possess itβ (Deut. 19:14).
A βlandmarkβ is a mark that designates where your land ends and your neighborβs land begins. Modern surveyors drive a metal rod into the ground to separate and distinguish property, but ancient landmarks often consisted of a stone that could be removed by someone wishing to encroach upon his neighborβs land. God pronounced a βcurseβ upon any man who would dare to so mistreat his fellow-Hebrew (Deut. 27:17). This was because after God divided up the Promised Land amongst the children of Israel in the Book of Joshua, He commanded them that it not be sold (Lev. 25:23; Num. 36:7). This is why Naboth refused to sell his land to Ahab (I Kings 21:1-3). Naboth wasnβt beingΒ stubbornΒ orΒ disrespectfulΒ to his king, he was beingΒ faithfulΒ to the Law of his God (cf. Ezek. 46:18).
Landmarks to this day continue to mark where your land ends and your neighborβs land begins. However, today we also have certainΒ societalΒ landmarks that God has to help us distinguish between right and wrong. For instance, for thousands of years, mankind clearly understood where to draw the line between right and wrong when it came to the subject of abortion. Then in 1973, our Supreme Court removed the landmark when they legalized abortion, and we have been living with the holocaustic consequences of this βlandmark decisionβ ever since. Now societal surveyors are taking aim at yet another God-given landmark, the definition of marriage that limits it to the bond that can only exist between a man and a woman in the eyes of God.
Such landmarks also exist in the spiritual realm of Bible doctrine. The historic fundamentals of the faith that define Christianity have for centuries helped Godβs people determine where truth ends and error begins. These spiritual landmarks are always under attack, and the day in which we live is no exception. To counter this trend that was present even in his own day, the Apostle Paul challenged young Timothy:
βHold fast the form of sound words, which thou hast heard of me, in faith and love which is in Christ Jesusβ (II Tim. 1:13).
While we should always be open to receiving new understanding from Godβs Word βwith all readiness of mindβ (Acts 17:10,11), we must βprove all thingsβ and βhold fastβΒ only βthat which is goodβ (I Thes. 5:21). We have a rich βinheritanceβ in Christ (Eph. 1:11,14) that these landmark doctrines serve to protect. Letβs work together to preserve them! source
