Sin is the issue, the false church system, has the whole gospel backwards, leaving all the professed in their carnal minds, thinking the son came to set them free from His wrath, which could be further from the truth.
Act 26:18 To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith(faithfulness) that is in me.
In order for a radical transformation to occur in the heart, where the blood of Christ has turned them from dark to the light, from the power of satan to the power God, there must have been a real radical renovation of the soul.(2 Cor 7:10-11)
This renovation, or being made completely new again,(2 Cor 5-17) must be proven by the deeds(faith/obedience to truth) brought on through a major crisis of conviction that led to bitter repentance (Acts 3-19)and crucifying of the flesh,(Gal 5-24) where going back to any rebellious ways is over, never to be repeated again. (Matt 3-8).
If the eyes were truly opened, and a “release from bondage” (redemption) has taken place, then I do not see why so many who claim to have repented of their sins, fall back into their rebellious ways after a supposed conversion. (Eph 1-18).
1Jn 3:9 Whosoever is born of God doth not commit sin;(produce) for his seed remaineth in him: and he cannot sin, because he is born of God.(Born again).
Being born of God requires a radical transformation of the soul! Where the seed of God is now planted in the heart, and now committing any rebellious sins against Him, (Gal 5:19-21) and I mean those pre meditated, well planned and thought out sins of the flesh, that are driven by rebellion, lust, hate, envy, revenge, etc. are totally removed from the heart, mind and soul, now replaced with the laws of God, (Heb 10-16) upheld by faith or faithfulness to those laws. (Righteous requirements) Now going back to your vomit (Prov 26-11) either shows you were never converted in the first place or you were, and now will have a very difficult time if not impossible to come back again, and find that real repentance that brought you into His light once and for all.(Heb 6-10, 10-26).
We will never be perfect in knowledge or understanding, we make mistakes, and have faults, God has given us emotions that act as a warning for us to check our hearts, as to worry leading to sins of the flesh, or anger leading to hate, murder, and violence, foul language, as well as fear and loneliness leading to breaking away from God and into worldly lusts. (James 1:13-15).
But IF you are still struggling with sins of the flesh, then no real radical transformation has taken place in your heart, because those who still struggle with these type of sins, either say they were born again in this state, (condition) or that they can claim 1 JN 1-9 or 2-1(easy forgiveness) after a fall, and simply find repentance again! This will show that they are still carnal, (Rom 8-5-6) but still have a chance to come clean with God once and for all! (Rev 2-5) Never to look back, (Matt 16-24) while they count the cost of dying to self, (Romans Ch 6)and living for Christ,(Luke 14:28-30) filled with His spirit, and power, to never have to make the excuse they fell back into sins of the flesh.(1 Cor 6:9-10-11).
A real renovated(redeemed) convert who does the unthinkable(going back to vomit) is either insane, or has just thrown out all those precious and exceedingly great promises by God,(2 Peter 1-4) who said He will always give a way out of temptation,(1 Cor 10-13) plus never give us more than we can bear! Making a second repentance a real dilemma, where going through real godly sorrow again, (2 Cor 7;10-11) will require possibly months to years of sever brokenness and contriteness, trying to find mercy again, after trampling on the blood, counting it as dung! A real converted soul will never go there, not because they are special or better than the rest, but because they have done their first works right,(Rev 2-5) and a real radical transformation has occurred (taken place) in the heart and soul, (cleansing and purging by the blood)(Heb 9-14) and they know that going back to their vomit(2 Peter 2:20-22) would be the most hateful, selfish, foolish, and evil thing they could do before God who has set them free,(John 8-36) and made them a holy nation and a royal priesthood in His name!(1 Peter 2-9).
Rom 6:7 For he that is dead(to sin) is freed from sin.
Death is permanent, and so should the repentance you went through to put the flesh to death once and for all!
