At its' most basic level, Dispensationalism is simply Distinctions in Identities or Things That Differ.
In this, a much earlier form of these Distinctions in Identities can be found in God's Words to Israel through Moses as to the Distinction in Identities in every way, shape and form, between Israel and the Gentile Nations.
Deuteronomy 4:1 Now therefore hearken, O Israel, unto the statutes and unto the judgments, which I teach you, for to do them, that ye may live, and go in and possess the land which the LORD God of your fathers giveth you. 4:2 Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the LORD your God which I command you.
4:5 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. 4:6 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. 4:7 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? 4:8 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? 4:9 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; 4:10 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.
Not surprisingly, the Apostle will assert something similar to the above many centuries later, not only as to the need to not depart from Paul's distinctive "my gospel" but to the need to be very diligent in attempting to seek to not deviate from the Lord's Words through him:
2 Timothy 2:1 Thou therefore, my son, be strong in the grace that is in Christ Jesus. 2:2 And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also. 2:3 Thou therefore endure hardness, as a good soldier of Jesus Christ.
2:7 Consider what I say; and the Lord give thee understanding in all things. 2:8 Remember that Jesus Christ of the seed of David was raised from the dead according to my gospel: 2:9 Wherein I suffer trouble, as an evil doer, even unto bonds; but the word of God is not bound.
2:14 Of these things put them in remembrance, charging them before the Lord that they strive not about words to no profit, but to the subverting of the hearers. 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. 2:16 But shun profane and vain babblings: for they will increase unto more ungodliness. 2:17 And their word will eat as doth a canker: of whom is Hymenaeus and Philetus; 2:18 Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some. 2:19 Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
Luke 12:42 And the Lord said, Who then is that faithful and wise steward, whom his lord shall make ruler over his household, to give them their portion of meat in due season? 12:43 Blessed is that servant, whom his lord when he cometh shall find so doing. 12:44 Of a truth I say unto you, that he will make him ruler over all that he hath.
