Hebrews 10: although law demands perfection, it can NEVER make the comers thereunto perfect, being imperfect itself, only a "shadow" (dark version).
Do the will of God PRECEDES receive the promise.
Will of God: I will have mercy, and not sacrifice.
What does it mean? I will have grace, and not law.
Law is good, but "both good and evil" ends evil.
Grace is also good, but it's always good "only".
Law is holy, but also among "unholy": 2Timothy3.
Grace also holy, but never among unholy things.
Law is spiritual, but spiritual perversion and abuse.
Grace also spiritual, but never perferted nor abusive.
The GRACE of our Lord Jesus Christ with you all. Amen.
