So the question - Does God introduce hardship-difficulty-suffering etc...? Consider a perspective. Adam and Eve have just been put in the garden. They are standing there without history, no parents, no memory, no past, just there. One minute they were not and then they were. Two adults in a world previously unknown to them. God gives them each other (marriage), a job (work the garden), enjoyment (food and things "pleasing to the eye) and trial (hardship). Their trial (testing, not temptation) was the freedom "you are free to eat from any tree in the garden" except for the tree of knowledge. So, their suffering was their decision (God does not make it for them) to believe (have faith) in what God said (if you eat of it you will die) or ignore God and do their own thing (See Gen. 3). God built the dilemma into their world. He did not tempt them to eat (Satan did that) but he did present them with the choice. The choice was a dilemma and we only have part of Eve's decision making process in Genesis 3(I assume it is only part). The mental and spiritual struggle to obey was by God's design. He created them, informed them, warned them and let them go. They had the hardship, suffering, difficulty of deciding.
POINT: Hardship, suffering (excluding temptation) was part of God's created order. If we suffer it is natural..expected...normal...Foree
