If u wear a cross necklace does this mean your going to heaven and your not a sinner?

I wear a cross necklace because I like the way it looks and it was a gift from my husband on my 31st birthday. I don't wear it for any other reason than that. Going to heaven? A non sinner? Hahahahahahaha! Stop it Otis, you're going to make me wee my pants.

Nope. It means that you like to wear a cross, that's all.

Yes, Otis, it is just that simple.  Bam! Here's your necklace!!!

Crosses are easy to grab.

---Makes it easier for either God or the devil to get ahold of you.

Simply put .. No. It doesn't mean someone has a one way ticket to heaven, nor does it mean that person is not a sinner.  Not even remotely close .

A fashion statement with a religious symbolism?. It certainly CAN imply those things to religuous people who DO believe those things to be true. But it doesn't make any of those a fact. Or define a person to that.

Am I wrong?  Anyone can wear a cross regardless of their faith or religion.

Lets not label anyone.

As a child I was given one by my mother and use to think that it would protect me. However, I'm really not sure where the cross comes into Christianity because Jesus had to be hung on a "tree" in order to fulfil the curse? Deut 21:23 Unless there is an allegorical meaning?

The cross has been a symbol for many years and means different things, with variation of the symbol itself, i.e the Tau cross versus the one Constantine claimed to see which was in fact an X,  the cross of the zodiac + where all sides are even, the wheel of life, etc.  The cross was also seen as a crossroads where the current world met the afterlife and certain Lao (voodoo) could (which were made synonymous with the saints of the RCC), could be summoned, i.e. Going to the cross roads the place between heaven and earth where you could do a deal with Papa Legba. The axis mundi again a place of meeting between heaven and earth. 

So when the Jesus says take up your cross and follow me, what exactly does he mean? Some say that "cross" was a misinterpretation. However, since the cross is a symbol of torture some may see the cross a triumph over death, or the death of the "worldly" self.

Matt 16:25 "For whosoever shall save his life shall lose it, and whosoever shall lose his life for my sake shall find it. For what is a man profited, if he shall gain the whole world, and lose his own soul?

So I gather that the cross is not a pass for Heaven, or a membership reminder,in the bible it acts as an symbol of the task at hand.

No, because the cross is a pagan idol and God condemns it,1 John 5:21 " Little children,guard yourself from idols.  The bible states what is needed to be invited into God's home,Heaven, and wearing a pagan symbol that he condemns will not get anyone their.

Usually just a statement of one's faith or at the very least the indoctrinated beliefs that one holds in passing regard if not in total dedication.

Of course not.  Depending on the wearer, it can be a simple reminder of faith ... Or of a loved one who gave it to them.
