I don't know the answer to the pre/post tribulation question, but I do have questions of my own:
-If we as Christians are filled with the Holy Spirit and during the tribulation the HS is removed from the earth.......how does that jive with God will never leave or forsake you?
-Why would God want those whom he already holds in his hand to have to suffer the GT prior to receiving our reward?
I don't understand how that could be. Doesn't that go completely against the nature of God? He loves us and we have asked for and received his gift of eternal life ..........but he wants us to suffer without him for the last 7 years of our time on earth?
Good post. It is good to see one who knows the Word addresses those two things.
Being chiast, lest start with the latter:
It is interesting how the pre trib crowd holds that God wouldn't let His church go through the trib, so they are raptured beforehand. Yet they see the Word speak of believers in the trib, so they say that they are those who are saved in the trib. So then if God wouldn't let the "mature" church go through it, why on earth would He let the infant go through it? Stupid logic. There's no other word for it. it's just stupid logic.
That being said, I am not saying that you are in the group. far from it, as stated by your posts, it seems.
The israelites suffered a number of the plagues, but not all of them. Have you studied this out? Much of the OT is a picture portraying spiritual truths. i recommend studying it out, and it will give insight into your second quesiton. Take time, even years, to study and learn from God. if you always just have the answers dropped on your plate, you don't know how to study, and you don't learn from God, but man. That is foolish. There are no shortcuts to wisdom in Christ.
As to your first question, again, the OT sheds light on it. However, I am confident that one can stick strictly to the NT, as in the second question of yours, but the OT sheds much light on it. In the NT, and in that passage expressly, I think that you will find parameters given. Check the context. For a bit of a foundational work, study out the OT usage of the word "everlasting". this gives much background for reading the NT. this is not to negate anything in the NT, or the OT, by any means, but when understood in light of how it is used in the Word, we get an understanding and insight into the context and constraints of statements in the NT. Cool stuff. I struggled with the same first question as you, many years ago. I spent years on it, off and on, with the Lord teaching me in other things, before I could understand this one. Others will be given understanding on this one, and that will be used for understanding on other ones. God is God, and teaches and instructs as He wishes, per person. It's a blast.
"Wait upon the Lord. And again I say, WAIT!" Much wisdom in that, from God Himself. Listen to Him.
