There are things in this life that it would be beneficial to forget, yet there are many others we would do well to not forget and scripture teaches us what that is. We are given good advice in proverbs that by not forgetting Gods laws and commandments we will find favor in the sight of God and man. (Proverbs 3:1-7). My son, forget not my law; but let thine heart keep my commandments: For length of days, and long life, and peace, shall they add to thee. Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart: So shalt thou find favour and good understanding in the sight of God and man. Trust in the Lord with all thine heart; and lean not unto thine own understanding. In all thy ways acknowledge him, and he shall direct thy paths. Be not wise in thine own eyes: fear the Lord, and depart from evil.
It is so important to God that His way always be taught, and we see this in Moses address to Israel that they do not forget what they had seen before entering the promised land and to make sure and teach their children to reverence and fear God.(Deuteronomy 4:5-10). Behold, I have taught you statutes and judgments, even as the Lord my God commanded me, that ye should do so in the land whither ye go to possess it. Keep therefore and do them; for this is your wisdom and your understanding in the sight of the nations, which shall hear all these statutes, and say, Surely this great nation is a wise and understanding people. For what nation is there so great, who hath God so nigh unto them, as the Lord our God is in all things that we call upon him for? And what nation is there so great, that hath statutes and judgments so righteous as all this law, which I set before you this day? Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons’ sons; Specially the day that thou stoodest before the Lord thy God in Horeb, when the Lord said unto me, Gather me the people together, and I will make them hear my words, that they may learn to fear me all the days that they shall live upon the earth, and that they may teach their children.
We must never forget God for any reason, for in doing so His message is loud and clear for such wickedness and to those who hate His instruction.(Psalm 50:17-23). Seeing thou hatest instruction, and casteth my words behind thee. When thou sawest a thief, then thou consentedst with him, and hast been partaker with adulterers.Thou givest thy mouth to evil, and thy tongue frameth deceit. Thou sittest and speakest against thy brother; thou slanderest thine own mother’s son. These things hast thou done, and I kept silence; thou thoughtest that I was altogether such an one as thyself: but I will reprove thee, and set them in order before thine eyes. Now consider this, ye that forget God, lest I tear you in pieces, and there be none to deliver. Whoso offereth praise glorifieth me: and to him that ordereth his conversation aright will I shew the salvation of God.
