Doo u think it's possible to overcome temptation...with out the Holy Spirit!?

I do it every day. I find it sad that some can not.

Love the lightning photo! The Spirit of God is mentioned a lot in the Bible (in every translation). Psalm 51:11 is a plea to God not to take his Holy Spirit away but several times in the OT that's what happens, with devastating results. And another point in the Bible is that people succumb to temptation even when they DO have the Holy Spirit! Peter was tempted 3 times to deny Jesus, and he did. But that did not mean he had the Holy Spirit removed. He grieved the Holy Spirit, but upon repenting he was restored.

1 Corinthians 10:13  No temptation has overtaken you except what is common to mankind. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can endure it.

1) People have overcome temptation, including myself

2) There are no spirits, holy or otherwise.

So yes.  QED.

Absolutely possible.

I'm an atheist who will be celebrating 6 years of sobriety in April after spending over 20 years of my life hooked on a variety of drugs.

I attended N/A meetings, where, as part of their program - I was told that in order to get and stay clean that I would need to surrender to a 'higher power'.  Since I didn't (and don't) believe in 'god(s)', then this presented me with something of a dilemma.

N/A gets a bad rap from some people for having what they view as a 'religious message' due to this 'higher power' concept, but then religious people (Christians especially) get down on them because this 'higher power' isn't 'Jesus' specifically.

In reality, most of the addicts that I met viewed this 'higher power' concept much more nebulously - just something to get you out of your own head, and focused on recovery.  Obviously some were theists, and so they had a ready made 'higher power' in their 'God', but once I found that it was not necessary to define it - that allowed me to get past my aversion to the concept.

Your 'higher power' could be a coffee mug - it just had to be something external.  (My coffee mug also has the distinct advantage of continuing to exist, even after I stop believing in it).  In the end, I was able to get (and stay) sober through a combination of willpower, changes in the people/places/things I was around, and the help of other addicts - who could help keep me accountable.

It must be possible.

Because the holy spirit is make-believe.

Uh . . . "without", not "with out."

"For if that first covenant had been faultless, then should no place have been sought for the second" (Hebrews 8:7)!

Consequently, 

"For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:

And they shall not teach every man his neighbor, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.

For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more" (Hebrews 8:10-12)!@

a devil worshiper can overcome temptation to kill someone, is that done by the Holy Spirit?

overcoming temptation is merely a person not doing something that they know is wrong to do. Which anybody can do this, even an Atheist or a devil worshiper.

However if a person wants to walk as Jesus Walked, they most certainly can't do it without the Holy Spirit. Even as i do all things to please Jesus Christ.
