They just redefine repentance to suit their agenda. It's not the real deal.
It seems that the hypergrace adherents accept repentance as valid concerning the sinner, but once saved they consider themselves to be exempt from any further repentance as children of God who certainly do sin in yielding to the flesh in some way or other.
For such occaisions, it was the apostle John who wrote in 1 Jn.2:1-2 "My little children, I am writing these things to you so that you may not sin. And if anyone sins, we have an Advocate with the Father, Jesus Christ the righteous and He Himself is the propitiation for our sins; and not for ours only, but also for those of the whole world."
The two verses, as well as the last portion of the verse shows that repentance is not just for sinners to be saved, but for Christians as well to be cleansed of sins as they commit them.
So the verses 1 Jn.1:8-10 apply to Christians, we know that it does because of the words "we", and "us", and "our". If John was addressing only the gnostics, then he'd use the words "you" or such and certainly not include himself and all Christians as gnostics and therefore subject to the verse. However, it's not addressed to the gnostics only, it is addressed to Christians, "If we say that we have no sin, we are deceiving ourselves and the truth is not in us. If we confess our sins, He is faithful and righteous to forgive us our sins and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar and His word is not in us."
How would a Christian say that they have not sinned? Perhaps by saying that they aren't required to repent because all their sins, including future as yet not committed sins, were forgiven at the cross of Christ.
There is no scripture in which future sins are forgiven before a person could commit them.
The hyper grace adherents give their response by claiming that Jesus forgave all on the cross, including those not born yet. Therefore, to them that would include their future sins. However, if that's true, then all of the sinners not born yet at the time of Jesus' crucifixion, would never have to repent in order to be saved.. because all their future sins were forgiven too.
Perhaps that is why the Holy Spirit through John wrote the verses I've posted above, to show that repentence is necessary for salvation, as well as for any sins committed by a Christian at any present time.
Sin certainly has not been abolished, so no matter who we are, repentance still applies.
I'm not speaking of legalism. I am speaking about a child of God responding to our Father's love, in His and our desire to be in the closest and most blessed relationship that He has provided.
God forgives because He so loves us. We repent because we so love Him.
