Of course, if we outright do not believe there is no such thing as prophecy it will hurt our understanding. Actually many have such an outlook, even of those who consider themselves sincere Bible believers. Many have listened to so many opposing interpretations of the same prophecy that they do not consider it possible to understand what these things mean.

For some that is true of Scripture generally.

Satan tries to make sure that hundreds of bogus
interpretations are floating around
just to confuse us.

This often works. Even scholars often are so dazzled by the excess of interpretations, that even they often think that there is no for sure way to understand these things. That is a basic strategy that Satan uses in seminaries and in life, to disillusion us.

The truth is that Scripture IS rational and consistent,
although it may at times use thought
patterns with which we
are not familiar.

At times we may want to put the blame on Scripture, but the real blame may be with false perspectives which we have often unconsciously absorbed. Satan, and the mystery of lawlessness, and Mystery Babylon the Great try to continually seed us with false ideas (Mtt 13:24-30, 36-39). Intellectual mine fields and snares and traps lie all around us. Literally.

The Bible is rational and consistent, and also it IS inspired of God, and can give us the right answers, IF we will use it correctly. That takes some study and some practice. If we have absorbed some false ideas, and all of us have at times, we can sort them out by patiently and carefully using Scripture.

None of us EVER understand everything
perfectly.

“But if anyone thinks that he knows anything, he doesn’t yet know as he ought to know.”
1Cor 8:2 WEB

Abraham was a faithful man of God. He definitely believed anything God said. So of course when he was commanded to sacrifice his son Isaac as a burnt offering on Mount Moriah (later know as Mount Zion), then he proceeded to comply (Genesis 22). Of course, God was just testing him, and stopped Abraham before he went to kill the son though whom God had promised him rich and great promises. Scripture tells us that Abraham was,

“accounting that God is able to raise up even from the dead. Figuratively speaking, he also did receive him back from the dead.”
Heb 11:19 WEB

That is some insight into how true faith really works. Even if we are misunderstanding some things, faith always gives God the benefit of the doubt, always assumes God is right in what He says.

Focusing on ourselves or the interests of the
world will always blind us.

Peter was trying to talk Jesus out getting ready to die in Matthew 16.

“But he turned, and said to Peter, “Get behind me, Satan! You are a stumbling-block to me, for you are not setting your mind on the things of God, but on the things of men.””
Mtt 16:23

Not setting our mind on the things of God will blind us to prophecy, and many other things.
