All those Christ died for, that is, obedient unto death, by His obedience, all for whom He died shall live by Faith. The scripture says, that the Just shall live by Faith.
rom 1:17
For therein is the righteousness of God revealed from
faith to
faith: as it is written, The
just shall live by
faith.
Gal 3:11
But that no man is justified by the law in the sight of God, it is evident: for, The
just shall live by
faith.
heb 10:38
Now the
just shall live by
faith: but if any man draw back, my soul shall have no pleasure in him.
This is important, and this will show us that by Jesus Christ death alone, it effects Faith in the lives of those He gave himself for.
Rom 5:
19For as by one man's disobedience many were made sinners,
so by the obedience of one shall many be made righteous.
Now, Paul declares in His Gospel here, that by the obedience of one [That being Christ] many shall [ a promise] be made righteous !
Now the word for righteous here is the greek word
dikaios which means:
) righteous, observing divine laws
a) in a wide sense, upright, righteous, virtuous, keeping the commands of God
1) of those who seem to themselves to be righteous, who pride themselves to be righteous, who pride themselves in their virtues, whether real or imagined
2) innocent, faultless, guiltless
3) used of him whose way of thinking, feeling, and acting is wholly conformed to the will of God, and who therefore needs no rectification in the heart or life
a) only Christ truly
4) approved of or acceptable of God
The word is also translated Just as in rom 1:
17For therein is the righteousness of God revealed from faith to faith: as it is written, The
just shall live by faith.
It can read, the righteous shall live by Faith !
Notice the word shall again ? Its a promise, the promise is, the righteous or the Just shall, no question about it, shall live by Faith.
This means
unequivocal that all whom Christ became obedient for, by His one obedience,
they shall be made to live by Faith. Because they shall be made righteous or just by His obedience, and the promise is the righteous or Just shall live by Faith..
So the death of Christ
ensures Faith to all for whom He died. None He died for can remain a unbeliever, that would defeat the effects and promised blessings of His death..
And consequently, those never believing or having Faith, He never died for them..
