I agree.I am dispensationalist also. I agree with Ironside, as shown in the link you gave, that ultra-dispensationalism is no good.
But concerning dispensationalism, I do not think one can ever come to a complete understanding of the Scripture without understanding the dispensations God has given us in the Scripture.

No one can read the Bible and not see God set up blocks of time which changed in the amount of revelations he gave in each progressive one.
Change the revelation and change the realities.
Salvation has never changed. But the amount of knowledge we have has changed, which changes what we are judged upon.
The more we are given the more is required.
