This can be a controversial question, but the answer is none the less Yes we can and indeed should.
The real question is not can we but "how" can we.
The answer is only found in Jesus and the promises of God.
Most fail on this point because they think about human weakness but we would do well to learn the lesson from Abraham:
Rom 4:19 And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sara's womb:
Rom 4:20 He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God;
Rom 4:21 And being fully persuaded that, what he had promised, he was able also to perform.
Rom 4:22 And therefore it was imputed to him for righteousness.
Notice that when it came down to it, Abraham did not consider his weaknesses or inability to do it. But rather was strong in faith trusting that Gods promises were true and that God would make it happen.
This lesson is for us as it is written:
Rom 4:23 Now it was not written for his sake alone, that it was imputed to him;
Rom 4:24 But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead;
Rom 4:25 Who was delivered for our offences, and was raised again for our justification.
So stop looking at your problems and start trusting Jesus as your solution and see what happens.
Go look at all the promises God has in his word about no longer sinning then claim them because:
2Co 12:9 And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me.
and:
2Co 1:19 For the Son of God, Jesus Christ, who was preached among you by us, even by me and Silvanus and Timotheus, was not yea and nay, but in him was yea.
2Co 1:20 For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.
Be joyful for greater is he that is in you than he that is in the world.
Ask God to show you your sins and when He does don't resist but surrender it to Him and He will take it form you and you will be victorious then ask Him to fill that spot with himself and you will see your life change form Grace to Grace and faith to faith until you reflect His Glory fully and you can say with Paul:
Gal 2:20 I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me.
