It has been a few decades since I was taught a bit of the Greek. Was my teacher incorrect, or does my memory fail me concerning the ‘Ifs” in Scripture. It seems that I recall there were 3 primary if’s;You do hate those IF's.
You said:
Notice that this is essentially a repeat of verse 6, in which we read: but Christ was faithful as a Son over His house - whose house we are,
(demonstrative evidence) if we hold fast our confidence and the boast of our hope firm until the end.
The wording is not - "and you will become partakers of Christ (future indicative) if you (future indicative) hold fast." It is rather - "you have been and now are a partaker of Christ" (demonstrative evidence) if in the future you hold fast the beginning of your confidence steadfast to the end." Holding fast is proof of genuine conversion.
Yes, mailmandan...
it is WHOSE HOUSE WE ARE
IF
WE HOLD FAST....
The IF above does not require any future tense to be demonstrated.
We are the house IF we hold fast.
We already are the house...
IF
we hold fast.
Holding fast in the condition required to REMAIN God's house...
to REMAIN partakes of Christ.
Paragraphs to explain that pesky little word...
IF
They are partakers NOW...this is the part you do not like.....
IF they REAMAIN.
Always an English lesson instead of a soteriological lesson.
BECAUSE
You cannot get around what it means in plain English.
1- If, and “it may or not be true.”
2- If, and “it is true.”
3- If, and “it is not true.”
I also understand that the nuance in any given verse depends on the Greek construction, not just the English word “if,”
So, how one understands those “If” statements does seem to be based on ones theology as well as the Greek.
