Do we have no control over our flesh? This is from a Facebook fan page titled "Jesus Christ":


  We all struggle with sin, and at times it's so bad that we think" God has to hate me,I will never get into heaven, I am so awful!" Well Thats the devil talking to you and the truth is we have NO control at all over the lusts of the flesh. We have to have faith and trust in God, that He is going to get us through it by walking in the spirit! You know you can't say NO to what you feel inside or want to do, no matter how hard you try. I know I cant! So tell God you are sorry and ask God to take it for you and trust in Him! If we try and do it on our own like in Deuteronomy it will take us so much longer to accomplish what God wants because we didn't trust in Him. If we truly give it up, it's at that point God takes it and it's easy!He knows it's not easy but He tells us we just have to be willing to give it to Him and He will do the rest.And if it comes back up for you again give it right back to God!And just keep doing it and after a while you will be amazed what Happends!Don't be affraid! Walk in the spirit! We walk by faith not by sight!God can handle anything! Jennifer GSM


The emphasis is mine and is the inspiration for this question. When I read this, I kept thinking that that was so wrong. I myself can control and suppress certain fleshy desires and without any perceptible help from God...and so can others, including non-Christians. I could be wrong though. Hence, I'm wondering: is this view Biblical?
If we have no control over the lusts of the flesh, then all the commands in the Bible to refrain from sin are pretty absurd and waste of time and space.

Of course we have the ability to say no to temptations, as is cited in many passages of Scripture that urge us to do so.


  No temptation has overtaken you that is not common to man. God is
  faithful, and h*e will not let you be tempted beyond your ability*,
  but with the temptation he will also provide the way of escape, that
  you may be able to endure it.  1 Corinthians 10:13 ESV
  
  For the grace of God has appeared, bringing salvation for all people,
  12 training us to renounce ungodliness and worldly passions, and to
  live self-controlled, upright, and godly lives in the present age. 
  Titus 2:11-12 ESV
  
  As obedient children, do not be conformed to the passions of your
  former ignorance, 15 but as he who called you is holy, you also be
  holy in all your conduct, 16 since it is written, “You shall be holy,
  for I am holy.”  1 Peter 1:14-16 ESV


If we really did not have the ability to overcome temptation, then the Bible would say much different things and give different instructions about responding to our inevitable failures.
