one might think if Revelation troubled them, so would Daniel, Ezekiel, parts of Jeremiah and Isaiah, Matthew 24, Mark 13, Luke 21, Jude, and if you're an avid reader Enoch.
for myself, it's a puzzle. not just any puzzle, but a puzzle holding absolute "Truths."
those Books have allowed myself to look at the current condition and state of mind this World we live in exists. and being able to recognize what is trying to be hidden reveals many clues. but with all of the Clues connecting the Prophecies, the reality is like a closed door that has been kicked wide open. and looking through you will find the Promises of God for every Believer and denier. and that alone is both joyful and nerve wracking because time is short and so many lives need each one of us to introduce them to God. which makes us understand we have a serious responsibility here. and if we aren't trying to bring souls to God, what good are we to the Kingdom of God?
i look at it like just mentioning who Jesus is or telling them God loves them might just be the thing that if they deny God now, it will cause them to choose to be beheaded rather than take the MOB. that way, it is a Salvation point of impact.
