我們必須憑信心
acknowledge that we, human beings,
can never completely comprehend as
long as we are on earth.

Thus,
stop 爭執! (embrace 救贖100% from God and 100% because we believed)
stop trying to
explain anything crystal-clear into something puzzling!
As you, dear brother, did:

1. 基督的死償付了全人類的罪
but made MATH is not applicable
(提供和接受became兩回事)
Total= Jesus paid Total + 拒絕 的 人paid,
is it possible, Yes, it is possible, if He wish,
MATH (or any rule He created)is nothing,
but not likely, because no need.

2.無限救贖論則承認救贖的範圍既是有限的，也是無限的
funny statement, isn't it?!

3.當逾越節的羔羊被殺的時候，他們的罪已經被遮蓋了。
但是，如果他們不將血塗在門楣上，他們仍將被天使擊殺。
他們因此而付了第二次代價嗎？ anything true here?
anything comparable to 這些人在火湖...一罪二罰?!
first of all, I don't think Bible recorded any 以色列人
不將血塗在門楣上, if so, how dare you are to imagine
anything never happened to support your point, secondly,
the whole story 逾越節的羔羊的血 and 將血塗在門楣上 and 被天使擊殺
DIRECTLY pointed (never equal)to Jesus' 代贖,
Holy Spirit's dwelling (sign) and final judgment.

Practically there is no 實際的困難
if we just say what we know and what we are sure,

The fact:
1.基督 為所有的人代死 is debatable and not conclusive
2.基督 為選民 代死 is not debatable but conclusive and crystal-clear

why we cannot, based on Roman 1 and Gen.2:17, tell our beloved ones
THERE IS A BAD NEWS:
human being is under God's WRATH and is going to HELL directly
fortunately
THERE IS A GOOD NEWS: based on John 3:16,
if this person ask :' if I am not chosen by God, it is possible
that 基督的代死 is nothing to do with me'
we can HONESTLY answer:'how to know if any individual is God's chosen one,
we have an easy way to know : who accepts Jesus' salvation
is God's chosen one and who refuses Jesus' salvation is not'

see, we can spread the GOOD NEWS without using the-possible-white-lie!

we are just human beings who are very very limited,
say what we are sure,
do what we can,
never feel guilt about these!
