It may not be a salvation issue 'yet' but if the pre-trib theory is wrong - it certainly could become so.
I believed pre-trib for my first years of salvation but kept running across verses that seemed to contradict it and then heard Tim LaHaye say that they can't prove pre-trib with just the Scriptures and heard Keith Green say, be ready for either because he couldn't say just yet or boldly what he believed - so that's what led me to go to just the Bible and a Strong's and find every verse from the O.T. to the New that had anything to do with His 2nd Coming and write all that Scripture down in a notebook and surprise-surprise to me in 1985 when I did that and kept adding more & more from the O.T. as I'd find more each time I'd read through it. Just Scripture alone can be trusted whole-heartedly.
you are not far from the Kingdom of God, because you are like the Bereans. If you hear something that you don't agree with or have questions about, you do the Scriptures for answers. Because of this, the Holy Spirit of Truth will indeed reveal more and more to you.
A poster said this is not a Salvation issue and that poster is correct. You say
"It may not be a salvation issue 'yet' but if the pre-trib theory is wrong - it certainly could become so."
You are so right. The danger in believing pre-trib or post-trib, is they will not be ready when He appears.
The pretrib camp believes that Jesus will come BEFORE the Tribulation Period, So when it does start and He did not come, there will be a great falling away from the Faith. Because so many falsely believe He appears before it all begins, which is NOT Scriptural, it is a belief that man teaches, based on what man thinks is the Truth.
The posttrib camp will not be ready because when the Tribulation period begins, they will start their 7 year alarm clock, and will not be ready when He does show up in the middle of the Tribulation period, these will be the first ones to claim, that it could not be Jesus because it has not been 7 years yet since the beginning of the Tribulation period. Every eye will know it was Jesus on the day He shows up, but the very next day, they will think something else other than what is True.
Again many people will fall away from the Faith, because they though that Jesus would come before the tribulation period, and because He did not come when they thought He should have, they will be the ones who believe the man on TV saying "Where is your God now?" When the world is being bombarded by ACTS of God. And not just the Christian Faith will fall away, but all faiths in the World will fall away when the Wrath of God comes upon all the disobedient children of God.
So then it is the Falling away, that makes it a Salvation issue. NOT NOW, but then when the hour of temptation comes upon them.
