You are partially correct, because when the coming "great tribulation" starts, each soul is going to be holding on to what they believe going into it, and during it. The pre-trib rapture doctors try to claim there will be 'tribulation saints', those who will convert to Jesus 'during'... the "great tribulation", and they point those mostly being unbelieving Jews going in. But God's Word shows they will continue in unbelief all the way up to Christ's future return, and when they see Him coming in the clouds, they will wish for the mountains and hills to fall upon them because of their shame of having rejected Jesus as Messiah (See Zechariah 12; Luke 23 about "Blessed are the barren...")
Per Amos 8, God revealed in the latter days He would send a famine in the land, not for bread or water, but for hearing The Word of God, looking everywhere for it and not finding it. That has an effect upon people today, as He has closed off the spiritual ears of many just for the end of this world.
