No person can fully understand all things perfectly found in the scriptures, as those words are the revealed mind of God unto us.
I disagree, but to clarify, IF I live long enough, I think I will come to the point where I have a very firm grasp of everything that He has revealed in His word. Admittedly, I have a few areas I'm not sharp on, yet.
Why do I state this?
" For who hath known the mind of the Lord, that he may instruct him?
But we have the mind of Christ." ( 1 Corinthians 2:16 )
Believers actually have the mind of Christ Himself...that is what the Scripture says.
" Henceforth I call you not servants; for the servant knoweth not what his lord doeth: but I have called you friends; for
all things that I have heard of my Father I have made known unto you. " ( John 15:15 )
" For to one is given by the Spirit the word of wisdom; t
o another the word of knowledge by the same Spirit;" ( 1 Corinthians 12:8 )
" how that by revelation he made known unto me the mystery; (as I wrote afore in few words,
4 whereby, when ye read,
ye may understand my knowledge in the mystery of Christ)
5 which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit;" ( Ephesians 3:3-5 )
" But ye have an unction from the Holy One, and
ye know all things.
21 I have not written unto you because ye know not the truth, but because
ye know it, and that no lie is of the truth." ( 1 John 2:20-21 )
So, according to God's word, true believers know all things ( or will know as they study Scripture, which is how I understand it ). We also see this:
" All scripture [
is] given by inspiration of God, and
[is] profitable for doctrine, for reproof, for correction, for instruction in righteousness:
17 that the man of God may be perfect, throughly furnished unto all good works." ( 2 Timothy 3:16-17 )
All Scripture is given by inspiration and is profitable for many things...so that the man of God ( God's child ) may be perfect, throughly ( completely ) furnished unto all good works. To me, that perfection is a point in time when the fully grown ( spiritually speaking ) child of God will come to the place where he or she will completely understand God's word. Sound impossible? With God, all things are possible.
For me, I can in all honesty say that I am,
by the grace of God, getting to where I understand about 99% of His word. Again, God's children have the privilege of going straight to His word, and for Him to teach us all things...things that we will eventually understand.
As I see it, "Calvinism" versus "Arminianism" is not even the deepest we as His children can go, because most people who get this far, in my opinion, still have yet to resolve the "problem passages", which is part of what convinced me that "Particular Redemption" is true.
God has shown me how to resolve most of those passages over the years, and there is the occasional "hold-out", but I know He will show me when He wants to. My job is to keep reading.
Best regards,
Dave.
