Here's my problem with your thinking. If, as you say, we can attain sinlessness in the flesh thru Christ, what are we left with when we don't achieve this end ? If, as you claim, it is in our capacity to be sinless in the flesh thru Christ ...thru faith...thru fasting and much prayer.....whatever the case may be, there can be no excuse acceptable for even one transgression. Why ? Because something was made possible by God according to your teaching ......and we, if we fall have failed to obey perfectly. We are condemned not only by our transgression (breaking the law) but by our failure to obey perfectly as well. Now either our God expects us to be sinless in the flesh (because He made it possible and only the obedient will inherit the kingdom) or He recognizes that we will at times fall short of the mark. There can be NO IN-BETWEEN with the gospel you preach. If loving Christ means keeping His commandments to perfection after receiving salvation, then NONE will inherit His kindom......not a one of us. James 2:10.. For whoever keeps the whole law and yet stumbles at just one point is guilty of breaking all of it. and 1 John 1:8.. If we claim to be without sin, we deceive ourselves and the truth is not in us. So which is it ? Does saying that we can do all things thru Christ mean that we are condemned to hell if we don't actually achieve this end in the flesh ? Saying something is possible and demanding it's end thereof from others is a far cry from actually accomplishing it oneself. Why did the apostle Paul say ....Philippians 3:12..Not that I have already obtained all this, or have already been made perfect, but I press on to take hold of that for which Christ Jesus took hold of me. Did the apostle Paul qualify for kingdom inheritance though imperfect ? To say that others "use grace as a licence to sin" is to say that you know their hearts and their struggles. You have judged others and saddled them with a burden that you yourself (or none of us) can bear. Have you stumbled at even one point of the law since salvation ? Of course you have.....as have we all. But thanks be to God that.... 1 John 1:9.If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. None of us are righteous except by God's grace thru faith in Christ Jesus ? Lord.....be merciful to me a sinner. That is our only hope. And what a glorious hope it is.
