A sinner needs no works to obtain salvation and have his past sins forgiven.
Right...
But once he is saved, he better:
“…continue in the faith grounded and settled, and be not moved away from the hope of the gospel…” (Colossians 1:23)
Because:
“…faith, if it hath not works, is dead, being alone.” (James 2:17)
Well, but he
will, because, having been born again of the Spirit, and
because of having this new spirit in him, even the Holy Spirit ~ given to Him by God's grace through faith (Ephesians 2:8), because of this,
his will is then to do God's will. This is the natural result of being born again. We are God's creation, God's "workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them> (Ephesians 2:9-10).
Even so, just like Paul, we struggle against sin. Paul says:
"I find it to be a law that when I want to do right, evil lies close at hand. For I delight in the law of God, in my inner being, but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord! So then, I myself serve the law of God with my mind, but with my flesh I serve the law of sin."
And then immediately after, he says ~ of himself and all of us who are born again and in Christ...
"There is therefore now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. For God has done what the law, weakened by the flesh, could not do. By sending His own Son in the likeness of sinful flesh and for sin, He condemned sin in the flesh, in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit."
“Whosoever is born of God doth not commit sin; …and he cannot sin, because he is born of God.” (1 John 3:9)
Ah. The problem for many, Michlah-Imla, is the sense in which John says 'doth not' and also 'cannot'... and even more importantly the latter... in 1 John 3:9. So here is the verse in the ESV:
"No one born of God makes a practice of sinning, for God’s seed abides in him; and he cannot keep on sinning, because he has been born of God."
Point 1: That 'makes a practice' qualifier is very,
very important... the person who
makes a practice of sinning does so
intentionally and is
not repenting of his or her sin, and so is not born again of the Spirit.
Point 2: John means 'cannot' not in the wooden sense of not being able to do anything sinful, and therefore sinless, but rather in the sense of not wanting to keep on sinning, and battling or striving against sin, because he is penitent and wanting to please God... because he is of God, because God is his father, having been born again of the Spirit, and therefore loving Him and wanting to do God's will rather than the devil's (cf. John 8:44). John goes on to say in 1 John 4:19 that
"we love because He first loved us."
So:
“…sin no more, lest a worse thing come unto thee.” (John 5:14)
There are certainly
consequences, even for born-again Christians, for sin. But there is
condemnation no more. As John himself says in 1 John 1:8-9...
"If we say we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, (God) is faithful and just to forgive us our sins and to cleanse us from all unrighteousness."
And why? Well, it is because we are born again, and thus in Christ. But still...
"If we say we have not sinned, we make him a liar, and his word is not in us."
Now is this some kind of "license to sin"...? Of course not. Paul addresses that in Romans 6, saying...
"Are we to continue in sin that grace may abound? By no means! How can we who died to sin still live in it? Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with Him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. For if we have been united with Him in a death like His, we shall certainly be united with Him in a resurrection like His. We know that our old self was crucified with Him in order that the body of sin might be brought to nothing, so that we would no longer be enslaved to sin. For one who has died has been set free from sin. Now if we have died with Christ, we believe that we will also live with Him. We know that Christ, being raised from the dead, will never die again; death no longer has dominion over Him. For the death He died He died to sin, once for all, but the life He lives He lives to God. So you also must consider yourselves dead to sin and alive to God in Christ Jesus. Let not sin therefore reign in your mortal body, to make you obey its passions. Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness. For sin will have no dominion over you, since you are not under law but under grace."
Again, having been born again of the Spirit, we have this new spirit within us, even the Holy Spirit, and we strive against sin. Grace and peace to you.
