I still do not understand. Can you please enlighten me?
There were truths that applied Abraham, Isaac and Jacob that do not apply us today.
There were truths that applied to Noah that do not apply to us today.
There were truths that applied to Moses and the Israelites that do not apply to us today.
There are truths that Jesus and the apostles taught that do not apply to us today.
There are truths that DO apply to us today that did not apply to peoples in other dispensations mentioned above.
Rightly dividing the word of truth is not a matter of separating truth from falsehoods, it's a matter of separating truth from truth because not all truths apply to all peoples across all of time.
So, when people figure they have license to combine those truths of an adjacent dispensation with us today, that creates only confusion and chaos, such as making grace out to be something one must maintain because of commandments under an adjacent dispensation to persevere unto the end so that one SHALL (future tense) be saved; that contrasted with Paul's teaching that upon receiving grace after faith in the crucifixion, burial and resurrection of Christ followed by the SEALING of Holy Spirit in salvation at that moment (which is nowhere stated as being what is given in the adjacent dispensation), and thus no need to persevere unto end so that we SHALL be saved...we're saved right now, not at some future point in time on the basis of persevering.
Many people know to not combine the dispensation of Law into our lives today, while others DO believe the Law is still required for us today, with all of them picking and choose what they WANT to apply today from those other dispensations whatever fits with what they've been taught by their false teaching pastors and/or Sunday school teachers, etc., and/or what they WANT to believe.
For another example, look at the Hebrew Roots movement...they are firmly convinced that we are all still beholden to portions of the Mosaic Law, such as diet, festivals and observances, social, etc., and they remain clueless to the fact that they have fallen from grace. Borrowing elements of the Kingdom Gospel, and superimposing those things onto the Gospel of grace, and one has a system of belief with gross inconsistencies, for grace does not mix with works as the basis for its offer and operation in a life. Paul clearly argued:
Romans 11:6 And
if by grace, then [is it]
no more of works:
otherwise grace is no more grace. But if [it be] of works, then is it no more grace: otherwise work is no more work.
It is so simple, and yet so overlooked, with people thinking that they can somehow add works to the gift of grace, and thus make it better or more effective, and that simply cannot be the case. The OP is a prime example of the confusions that have arisen by trying to blend together two systems of truth, one of which was TO us and other not, with the other being TO them and not us.
Imagine going to work on payday, and your boss saying, "Here's a check for some money that is a gift," to which you reply, "Wait a minute, where's my paycheck based upon my work? I earned an actual paycheck. Thanks for the gift, but where's my pay for my efforts?" The insult is quite glaring, even though the masses of unprincipled and non-discerning out there would not care one way or the other so long as they got money, but the difference in the nature of what is handed over is indeed based upon two entirely different concepts that simply cannot be intermixed. It would be one thing to hire on with the understanding that receiving money on the basis salary level or hours worked would be acceptable on that basis, but NOT on the basis of earnings through a gift, and vice versa.
Does that help?
