Alltimejeff - I'll post some scriptures to respond to your last post, as these scriptures and subject should be black and white and easy for all to understand.
To address 2 things you mentioned, 1st is that, "anybody" can get understanding.
Matt 13:10-11 - Disciples ask Jesus why he speaks in parables instead of saying things black and white that all can understand, Jesus responds, "because it has been given to you to know the mysteries of the kingdom of the heavens, but to them it has not been given."
13:35 - "I will open my mouth in parables; I will utter things kept secret from the foundation of the world"
Matt 16:17 - blessed are you, simon Bar-Johnah, for flesh and blood has not revealed this to you, but My Father who is in heaven.
Matt 11:25 - I thank you Father, Lord of heaven and earth, that you have hidden these things from the wise and prudent and have revealed them to babes.
All of this is not to say that anyone is unable to get understanding. The scriptures also speak of a time when spirit is poured out on all, and also Jesus said those who ask the heavenly father for spiritual food he would give, and also in James it's written asking for Godly wisdom.
There are things that will for sure prevent one from getting it. For one, God is a reader of hearts, and will know your true intentions, even if you do not. He also will know the right time, if the current time isn't correct. James shows that if you ask, and have ANY doubts, your better off not asking, because you wont' get it. If your asking for holy spirit, but will reject anything that contradicts or goes against what you've believed, most likely will end there. It's not an easy road to seek out the truth like fine treasure and pearls, to give your life for it, to sacrifice everything. If you find on the path you may have to sell all your possession, to give up most of your life, at what point will you draw the line.
Those getting any insight also may have done NOTHING to deserve it. Remember the apostle Paul. But he took his correction and changed himself. Some may have to really seek it out, some God may choose for his own glory and have snatched them. But the point it, based on scripture, NOT everyone, NOT anyone, will get it and understand it, nor are allowed, only whom God and Jesus choose.
As for the timing of the information, although worldwide many may be on the same subjects or getting there, such as like an act of God. Everytime an understanding changes, even 1 slight detail, it may change or clarify the meaning of countless scriptures, so that having to rego over them, and more correct understanding brings forth more light. One can't understand calculus before learning addition and subtraction.
Some of my questions are for current things I'm working on, and some are to find any on the same page in that category to compare notes. I don't ask my questions so that anyone can answer or understand them, only if any have happened to go through the same topic already in their personal studies, it does not mean they are not privy to it on their own or never will be, but at the least they haven't done it yet, either their own choosing by letting other matters of their life take priority or not at that point yet. Based on what you can see in those above posted scriptures, I am very careful in what I publish for all to see, so as not to overstep and announce knowledge God may want to remain hidden for the time being or that somebody with bad intentions uses the information
