Dear JK,

Grace(not law) unto you, and peace(not division),
from God our Father and the Lord Jesus Christ.

The "grace" Noah found in the eyes of the LORD was neither pure grace, nor impartial; But grace + law, especially if Noah did both: "all God commanded" and "all the LORD commanded", which were contrary things. This sort of grace was partial to Noah and his family; To eight 'souls', who were perhaps not yet spiritual, but soulish, who all died and received not the promise: Hebrews 11, since do the will of God precedes receive the promise: Hebrews 10:36. And the will of God is: I will have mercy, and not sacrifice: Matthew 9:13 (from Hosea 6:6), which meaneth I will have grace and not law when studied out.

So we are to divide assunder soul & spirit: Hebrews 4:12, as with first Adam (soul) & last Adam (spirit) in 1Corinthians 15. But we are also exhorted to compare spirit (of error) & spirit (of truth): 1John 4, as "comparing spiritual things with spiritual": 1Corinthians 2:13, NT law vs NT grace... BECAUSE "as in Adam all die", whether it's first "Adam" or last "Adam". So it's a three stage progression to life void of death:
First Adam(die)-->Last Adam(die)-->Christ(live).

God forbid? Such a biblical phrase speaks of no, not this, but that; In such a comparative teaching: shew (plural of show) about law vs grace: about what is grace compared to what it's not: law, about what is mercy compared to what it's not: sacrifice, about what is peace compared to what it's not: division.

There is a matter of save some, but it's only to scuttle all perish (by grace + law), till we get to the end where none perish (by grace void of law). So with Noahic grace it was save some, to keep seed alive; But with JC grace and truth it's save all (the world) so none should perish by pure grace.

So another sort of "grace" came by JC: John 1:17. For the grace Noah found in the eyes of the LORD(LAW) was grace + law, which is as blessed + cursed = accursed, or as life + death = dead end; And for all if there is no respect of persons with God, no partiality, neither with Law is inexcusable nor with Grace is merciful.

The law foretold of grace, but the law also makes grace "no more grace". The law demanded perfection: Genesis 17:1, but law cannot make comers perfect: Hebrews 10:1. Only pure grace makes comers perfect(merciful) as our Father in heaven is perfect(merciful): Mt 5:48 (Lk 6:36). "Perfected" is past tense in Heb 10:14; 1Jn 2:5; 1Jn 4:12. Made perfect, via "the God of all grace" (no law at all) in 1Peter 5:10 is followed by strengthened, stablished, and settled; And after we've suffered awhile by law.

JK, you still perceive both comfort & discomfort; But there's no discomfort in "the God of all comfort". You still perceive both grace & law; But there's no law in "the God of all grace".

Perhaps you haven't (yet) noticed there's two of everything to sort out in the Bible; Perhaps even two sorts of law: OT LAW & NT Law: Romans 8:2, and also two sorts of grace: Noahic grace & JC grace.

For when studying out the Noahic sort of grace, it ended bad for all, even for Noah; But when studying out the JC sort of grace, it ends good for you all:

The GRACE of our Lord Jesus Christ with you all. Amen.
