Dispensationalism developed as a system from the teachings of John Nelson Darby, considered by some to be the father of dispensationalism (1800–1882), who strongly influenced the Plymouth Brethren of the 1830s in Ireland and England
This teaching is were alot of rubbish about God changing the way He rules comes from. The Bible doesn't support it.
It is a twisted belief and the God I serve doesn't change.
One rule for some and another rule for others. Disorder and no certainty, with dispensationalism, you can belief all sorts of laws and say it is a new order.. anything goes. God is the same yesterday and today. The Bible is the our only way to test all things.
Isa 8:20 To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.
Psa 19:7 The law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple.
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
The moral law has not changed....
