First of all I completely and totally believe in different dispensations. The Lord is dealing with people in different ways at different time periods throughout history. I have no clue why people says the bible doesn't teach it. It is all there in black and white. The Apostle Paul gave us instructions on handling and understanding the word of God when in 2 Timothy 2:15 that we are to rightly divide the word of truth. What in the world does this mean and why use the word "divide". Because all of the bible is written FOR us and our learning but it was not all written TO us. This is the main reason people get screwed up in their theology. In Peter he instructs the believer to understand and walk in the present truth. Now why is that? Because the present truth today Jesus died and rose and we are given eternal life when we believe that by faith. NO WORKS INVOLVED. But if you went back to Adam and Eve's time...what was the present truth? If someone told Adam the gospel he would have been lost. His present truth was do not eat of the tree of good and evil. If they had churches back in the day, that is what pastor would be preaching....DO NOT EAT OF THAT TREE. ok, fast forward to Moses and the law. During that dispensation, they were required to follow the law both moral and ceremonial. God was dealing these people under the law for about 1500 years. The law had it's purpose, it was to bring man to the end of himself so he understands how much he need GRACE. Of course, now we are in the grace dispensation and it will last until the rapture. I think covenant theology is wrong and dangerous and many of them believe that the church replaced Israel. That is impossible. God cannot lie and he made an everlasting covenant with Israel, he will fulfill it. I probably just confused you all the more but basically that is the long and short of it.
All history has different times (dark ages, war times, times of the kings, good time and bad times) and that isn't just for spiritual history but for any nation or people. And there is nothing wrong with dividing those times into different sections to understand the history.
But to
make a doctrine from this is a different thing.

"The Lord is dealing with people in different ways at different time periods throughout history."
Does God Change? Is God hard and harsh for 200 years than graceful for 300 years than change to being a king for the next 1000 years?
Are people save by works for a time than saved by grace for another time?
Heb 11:39 And
these all, having obtained a good report through faith, received not the promise:
By faith all are saved from Adam to the second coming. No change their.
Sure times and understanding and culture changes but God does not change.

Read 2 Tim 2 in context and try to do it without taking every word literally but spiritually.
2Ti 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.
2Ti 2:15
Study to shew thyself approved unto God, a workman that needeth not to be ashamed,
rightly dividing the word of truth.
2Ti 2:16 But shun profane and vain babblings: for
they will increase unto more ungodliness.
2Ti 2:17 And their word will eat as doth a canker: of whom is Hymenaeus and Philetus;
rightly dividing = to make a straight cut, that is,
(figuratively) to dissect (expound) correctly (the divine message): - rightly divide.
I think the verse in 2 Tim... is telling us to rightly understand the truth and not to get taken away by false doctrines.
i'd Ask people to read it in context and with pray asking for the Spirit to teach you. Because if it is falsely understood it can lead to a doctrine like dispensationalism.

It is possible because God did fulfil his promises, and the church is build on the promises, Paul makes it plan in Roms 11.
Rom 11:15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
Rom 11:16 For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.
Rom 11:17 And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;
Rom 11:18 Boast not against the branches. But if thou boast,
thou bearest not the root, but the root thee.
Rom 11:19 Thou wilt say then, The branches were broken off,
that I might be graffed in.
All the branches are in the same tree. gentiles and Jews, wild olive leaves and natural anyone can be grafted into the same tree. Same church.
read it all in context.
