Why don't fellow theists understand that the only thing that can take them to heaven or hell is the fruits of their actions?

That is not the truth.

It is not about what we can or can not do.

It is about Jesus Christ... who He is and what He has already done.

Ephesians 2:8,9

"For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;

not as a result of works, so that no one may boast."

If we had to work for it, it would be a reward... not a gift.

The "fruits" are the results of our love and caring... for the living God and other people.

emotional purity and good thoughts are also required

the fruits come from the roots, dude.

The Only thing that takes us to heaven is the Grace Of God given to us by the death and resurrection of Jesus Christ

you cannot earn your way to heaven

Yes but is it the mercy of God that allows successful afterlife. Not just deeds and efforts alone. And if I want to avoid wrath of God or major sins, praying is necessity. Praying is part of good deeds and yes, certain clothing is part of good deeds and obeying God.

There are words I say, words I need and seek my God with. Action is part of my faith than simply believing. The devil believes and acknowledges his Master as well but doesn't fulfill action. Doesn't pray, doesn't prostrate and doesn't do good in action.

So that they can sin, left and right, and still justify themselves that once saved always saved. They are only lying to themselves, not to God.

That's the position of every religion except historical orthodox Protestant Christianity.

Why do you not understand that both places are equally improbable?

That is not true. Christ died on the cross for our sins.
