Why do most people use apple to symbolize the forbidden fruit?

Men commit sin because of three things: lust of the flesh, lust of the eyes, and pride of life. God commanded Adam not to eat of the fruit of the tree to know good and bad. The snake tempted Eve to eat of it and Eve ate and gave Adam who ate also and there the fall of man was done. The apple especially the red one is very delicious to eat and that is lust of the flesh. The apple is very pleasing to the eyes, it's very beautiful especially the red one and so Eve was tempted and that is lust of the eyes. Satan said You will be like God (because that is the fruit of the tree to know good and evil) and Eve wanted to be like God, to know good and bad, and so she ate and that is pride of life. The Holy Bible did not say that the fruit is apple. The tree is identified as the tree of knowledge of good and evil. The apple is just use to symbolize the fruit of that tree because it is beautiful and pleasing to the eyes and very delicious to eat.

The apple is very appealing to the eyes and it's also very delicious and nutritious. It is very attractive so that it tempts people to hold and to eat it.

because it is red which also symbolizes seduction or temptation?

may be they do not read the Bible...or may lose in their reading of the Bible...because the Bible doesnt mention of the apple as the forbidden fruit.. what was written in the Bible was 'the fruit of the tree of knowledge of good and evil'....they use apple to make the story easy to remember...they simplified things so that people could easily take it/remember without considering what is the truth in the Bible...

I have no idea... tempting i guess. (it was good i don't like apples that much, hehe)

Interestingly enough, though the apple is the most common fruit used to symbolize the fruit of the knowledge of good and evil, this doesn't have any biblical origin I'm aware of. The Book of Enoch, which is not canonical scripture in most christian churches but is in some orthodox churches, describes the tree as bearing grapelike fruit. Various rabbi's have argued for other fruits, including figs and wheat. I've also heard some people claim it was pomegranates (in analogy to persephone in greek mythology), meat, or a hallucinogenic plant. Why an apple has traditionally been the artistic depiction, I don't know, though the strongest circumstantial evidence would seem to be from the similarity of the Latin words for apple and evil, as mentioned before.

also, in the Grimm fairy tale, Snow White, the poisonous apple looked so pretty on the outside, white with a red cheek, that everyone who saw it longed for it, but whoever ate a piece of it must surely die.

The red apple is very attractive and seems very delicious to eat and so it almost perfectly symbolizes the fruit forbidden by God to be eaten by Adam.

Because according to the book of Genesis, where it is the fruit of the tree of knowledge of good and evil eaten by adam and eva in the Garden of Eden. As a result of eating this fruit, Adam and Eva lost their innocence, began to know the good and evil.

It says no where in genesis what fruit it was but maybe there is something interesting being preserved regarding the original location of the story here. Apples originate in Kazakistan, that may sound odd, but apple trees do originate geographically in that region before bing cultivated all over the world. The Archaeologist David Rohl believes that there is firm evidence from geographical and place name research, as well as traditional stories and beliefs that the garden of eden story originates from near lake Van on the Iraq/turkish border. As Kazakistan is a near neighbour maybe the apple is logical and idicative of the location. Just a thought.

may be they dont read the Bible so they doesn't know the truth. the Bible doesnt mention of apple..it just mention 'the fruit of the tree of knowledge of good and evil'...
