It is very hard for them. They are forced to refute the bible. That is why they are so frustrated.
Funny how this goes both ways, no? :) You say this, but I'm sure the person you're arguing with thinks/says the very same about you. And he or she is right.
Aside from that, you just recently said, "Going personal is thread killer." Are you not doing that very thing here? You are... :) Maybe you think speaking in the third person ("them" and "they), you think you are able to dismiss that, but no... :)
God never ~ in all of Scripture,
never ~ promises removal from anything, tribulation included. He
always, in all of Scripture, promises to be
with His people, protecting and providing for them,
through it. I.E...
* As when, before the Exodus, the people of God were protected from God's wrath ~ even though they were present in the midst of it ~ by the blood on their lintels and two doorposts...
"...For the LORD will pass through to strike the Egyptians, and when he sees the blood on the lintel and on the two doorposts, the LORD will pass over the door and will not allow the destroyer to enter your houses to strike you. You shall observe this rite as a statute for you and for your sons forever." (Exodus 12)
...which pointed to the blood of Jesus protecting us even now... and to the end, the time of His return.
* As in Psalm 23, where David sings:
"Even though I walk through the valley of the shadow of death, I will fear no evil, for You are with me; Your rod and Your staff, they comfort me. You prepare a table before me in the presence of my enemies; You anoint my head with oil; my cup overflows. Surely goodness and mercy shall follow me all the days of my life and I shall dwell in the house of the LORD forever." (Psalm 23:4-6)
* Jesus says this explicitly:
"Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age." (Matthew 28:19-20)
Grace and peace to you.
