Fearing has a strange way of bringing to past what we fearor are afraid of. Read (Job 3:25); 'For the thing which I greatly feared is come upon me, and that which I was afraid of is come unto me'. Fearing sin leads to sin because of the flesh. This happens because many pulpits are preaching against sin and leave the listener in fear of failing instead of loving God. The strength of sin is in the law (1Cor 15:56). What that means is that we have the law of sin and death within our body (Rom 7:23). When we use the written law to preach against sin, without building on the foundation of the new birth that was made possible through Christ and the one new man that we have in Christ (Eph 2:15), the flesh will react against the law that is preached and the law of sin will be strengthened and served according to the flesh (Rom 7:25). The only way we can forsake sin is by building ourselves up in the love of God that came through Christ when He condemned sin in His flesh. We need to see that all our sin was nailed to the cross (Col 2:14). We need to know that we are not our sin. Paul said that when he sinned that it was, 'not I, but sin that dwelleth in me '(Rom 7:17). We are a new creature in Christ (2Cor 5:17, Gal 6:15), old things are passed away and all things have become new when we believe. God does not want that to be just positionally true but He wants it to be worked into us experientially because of the fellowship that He desires to have with us. If our sin is constantly being pointed out by others, that will only strengthen sin because pointing it out has no power to keep us from it. We are kept by the power of God (1Pt 1:5) and that power is the grace of God ministered to us through the Holy Spirit. We need to built up ourselves, and others, in the inner man (Eph 3:16), not after the flesh but after Christ (2Cor 5:16). We need to determine, as Paul did, to see one another according to Christ and Him crucified and not according to the flesh (2Cor 5:16). We should deal with sin in our own life before God and let others do the same. Judging believers, or getting them to fear sin, according to the flesh or the sins of the flesh does nothing to build them in Christ. In (John 12) there is no sin mentioned in the context of this chapter. Read (verses 46-48);
'I am come a light into the world, that whosoever believeth on me should not abide in darkness. And if any man hear my words, and believe not, I judge him not: for I came not to judge the world, but to save the world. He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day'.
Jesus Christ came not to judge the world but He did come to be judged for the world and to put away the sins of the world. Was John the Baptist wrong in his declaration, 'Behold the Lamb of God that taketh away the sins of the world'. Not just the sins of those who believe but the sins of the world. Should any of us forget that we were in darkness and in unbelief when God revealed to us the light of His glorious gospel? Do we forget what we are taught in (Eph 2:1-8);
'And you hath he quickened, who were dead in trespasses and sins; Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience: Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.But God, who is rich in mercy, for his great love wherewith he loved us, even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved), and hath raised us up together, and made us sit together in heavenly places in Christ Jesus: That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus. For by grace are ye saved through faith; and that not of yourselves: it is the gift of God'.
The cross dealt with the sin issue and we have received that cross through Jesus Christ death, burial and resurrection. Now we take up that cross to follow Christ and preach that cross as the salvation of God. The good news is the glorious truth that Jesus Christ is the sacrificial Lamb, who took away the sins of the world. And when a sinner, that is in the world, hears and believes in their heart this gospel that we preach, that Jesus Christ was raised from the dead, they have believed unto righteousness and are saved by grace through faith forever (Rom 10:10). This is not heresy, it is the gospel of Jesus Christ the Son of God who came to put away sin. If anyone preaches or teaches that men will go to hell because of their sin, that is blaspheming the the love of the Father who sent His Son and it is blaspheming the work of the cross, that His Son 'finished', that all men might believe (John 19:30).
There is nothing wrong with preaching against sin and convicting the sinner of his sin, but only in the context of what Christ did to sin because of the great love that God the Father has for all sinners. You can't preach against sin without giving God's provision for it. That provision is grace and love that will lead the sinner to turn from themselves unto God for salvation and deliverance from sin. When the children of Israel had rebelled and had sinned against the LORD in the wilderness, God sent fiery serpents to bite them, many got infected with the poisonous venom and died. The people, being sick, turned to Moses and confessed they had sinned by going against the word of the LORD. God then told Moses to make a fiery serpent out of brass, put it upon a pole and lift it up. Anyone that looked upon it who had been biten would live. The fiery serpent represented their sin before God. Brass represents judgment. The brasen serpent represented Christ taking on our sin and being judged. The pole is the cross that Christ died upon. What this speaks of is that we have been smitten with the fiery sting of sin before a Holy God. But God raised up His Son on the cross to be judged for our sin and all we have to do is look upon Him, who was judged, and we will live.
