The advice you get on questions like this can be good, but also bad and ugly. Those in line with the Scriptures are good - those not are bad and ugly.
I have to agree with the power to overcome mentioned by Seekingtoserve... as this is what the Scripture tell us to have faith in, God's power to change our lives and make us new creatures, the old passing away. It does not tell us to just wait helplessly in our sins until Jesus returns. That ugliness doubt and unbelief that comes from some people is in complete contradiction to the Word of God, though it sounds good to the flesh that wants to justify its continued sin without repentance.
YOU DO NOT HAVE TO CONTINUALLY SIN! I'm not the only one saying it, the Word of God says it.
2 Corinthians 5:17 MKJV So that if any one is in Christ, that one is a new creature; old things have passed away; behold, all things have become new.
John 5:14 MKJV Afterward Jesus found him in the temple and said to him, Behold, you are made whole. Sin no more lest a worse thing come to you.
Now, if Jesus could tell one not yet made new (born of the Spirit - John 3) to stop sinning, he surely is correct in telling us who are to stop sinning - and he will not tell us to do something we are unable to do with his help. The question is, are we trusting in his help and overcoming by the power he's given us? Or are we accepting defeat?
Romans 7:14-25 MKJV For we know that the law is spiritual, but I am carnal, sold under sin. (15) For that which I do, I know not. For what I desire, that I do not do; but what I hate, that I do. (16) If then I do that which I do not desire, I consent to the law that it is good. (17) But now it is no more I that do it, but sin that dwells in me. (18) For I know that in me (that is, in my flesh) dwells no good thing. For to will is present with me, but how to perform that which is good I do not find. (19) For I do not do the good that I desire; but the evil which I do not will, that I do. (20) But if I do what I do not desire, it is no more I working it out, but sin dwelling in me. (21) I find then a law: when I will to do the right, evil is present with me. (22) For I delight in the Law of God according to the inward man; (23) but I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin being in my members. (24) O wretched man that I am! Who shall deliver me from the body of this death? (25) I thank God through Jesus Christ our Lord! So then with the mind I myself serve the Law of God, but with the flesh the law of sin.
That is the perfect passage for your question. Yes, we struggle with this, as Paul said, but "who shall deliver me from the body of this death?" That is, the old corrupt flesh that wants to keep on sinning. "I thank God through Jesus Christ our Lord!" Then notice that he mentions two different natures - one in control of the new man in Messiah, and the other is old and of the flesh. The old and of the flesh wants to keep sinning, but the new man must overcome such.
This is what Seeking... was trying to tell you. That you can overcome, if you have been made new in Messiah. You do not have to keep doing the things you know to be wrong. Grace is not that God just accepts us as we are and then leaves us that way. Grace is that he has something better for us, that he accepts us as we are, though Messiah, but then CHANGES US from faith to faith and glory to glory until we are perfected in his image.
You must be daily about submitting to the Potter's work to perfect you in his image. If you aren't going forward, you are going backward, and that is called backsliding. Most believers I meet these days are lukewarm at best, and in a continual backsliding state though they keep playing church.
I can testify to you, that when I began to partake in the POWER of God to change me daily, instead of daily giving in to the temptation of sin, I've overcome much. I no longer do things on a daily, or even weekly basis, that violate the conscience or are scripturally found as "sin." I used to have all sorts of strongholds of sin in my life, and felt like "I just can't help it. I don't want to do this, but I just seem to have no power against it." Well, you don't! Not in yourself! Which is where HUMILITY comes in. To be humble before God, and admit you need his HELP to deliver you from the bondage of sin.
This is why Jesus said, "take up your cross and follow me." We must crucify the flesh and follow him daily. As you do so, over time, the flesh sin nature gets weaker and weaker, because you, by the power of the Cross and Holy Spirit aiding you, are killing it. Also at the same time, your spirit becomes stronger and stronger in Messiah.
Doing this breaks the cycle of weakness against sin, and puts you in a cycle of getting stronger and stronger, till one day you can praise God for his help, that you haven't had to confess anything for weeks! Or longer. Have faith, not doubt.
Doubt says, "Oh, that's impossible." Faith says, "By the power of his Spirit helping me I CAN DO IT!" For "I can do all things through Christ who strengthens me."
I affirm that you have grace while you grow and learn. But, I also want to get you having faith in the Word that he has said you CAN OVERCOME. It is a matter of SUBMITTING to him daily, taking up your cross to follow him, and dying to your old flesh ways. He never said it would be easy. But he promised to be there with all who submit, to help them by the sent Holy Spirit.
YOU CAN DO IT WITH HIM! Quit listening to the bad reports that say you cannot, and just learn to live with it. NO! Don't learn to justify your sin and live with it. Learn to conquer it, being more than a conquerer in Christ. Remember, there were only 2 witnesses in the wilderness among Israel that spied out the land and said, "We can do it!" The other 10 spies said, "We are but grasshoppers in their sight," speaking of the giants they didn't think they could overcome. Remember, there was a whole army of Israelites cowering before one giant. Yet, a young man who was a shepherd came up and said, "Is there not a cause!" Basically he was saying, "What are you all doing sitting on your butts, ye of little faith, when there is a giant to slay??" "Well, if you won't do it, I will, because God has helped me before, and he'll help me with this giant, for his namesake."
David went out before that giant without fear. How? because he knew the POWER OF HIS GOD, which is much greater than the little power that giant had. He was not trusting in himself, he was trusting in God to deliver him. I recommend you do the same. Listen to the 2 witnesses that preach faith in overcoming the giants in the land, not the 10 who say, "Just stay here in the wilderness and die with us."
Have faith in God - and faith without works is dead - so have living and active faith. You prove what you believe in your overcoming or lack thereof. It is easy to say "I believe," but how many really believe in the POWER OF GOD to change lives, making sanctified vessels for his glory? Not many, from my experience in many different churches and groups. Most people in churches are no different than ancient Israel. And they perish in the wilderness without receiving of the promises in this age.
I for one am continuing to go into the land of promises and take my inheritance, by the power of God with me. I invite you to join me on this most exciting adventure. There are certainly hard times, struggles, and tribulations, but we enter the Kingdom through many tribulations - the reward is WELL WORTH IT!! So come on, lets get to it!
** I speak to you as one who has overcome the following and not fell back into such destructive sinning
1. nicotine addiction as a smoker (2.5 pks a day)
2. cocaine addict
3. pot head
4. lsd tripper
5. pornography
6. fornications
7. lying
8. spiritual slothfulness
9. rebellion against God (running from him and his ways)
Ect. I've overcome many snares the enemy and my old flesh had me bound up in, by FAITH IN THE POWER OF GOD. If I can do it, so can you WITH HIS HELP! Only believe and submit to his working, taking up that cross daily to follow him, and dying to the old self.
Acts 14:22 MKJV confirming the souls of the disciples, calling on them to continue in the faith and that through much tribulation we must enter into the kingdom of God.
Your servant in Messiah,
David
