Christians why does your "God" refuse to hurt or kill atheists like me? ?

Why? Because He loves you so much He was willing to die a horrible death in order that salvation could be available you. You don't "hurt" people who are ignorant of a subject. You educate them.

God often chooses to ignore the insignificant and deliberately foolish, leaving them to their own devices, until Judgment Day.

Elohim is God, not YHWH.  Jesus Christ claims to be Jehovah incarnate, the creation and begotten son of God.

God (and learn to use quotation marks properly -- you'll look better educated) doesn't destroy you because he loves all of his human children equally.  Our spirits are literally his children, hence his love for us, hence his keen interest in keeping us out of eternal trouble.  Killing you would not help you prepare yourself for eternity.  When he destroys a civilization, it's to stop murder and other sins.

God isn't above working with our fears if that's the only way he can reach us.  He would much rather motivate us with love, honor, and duty and faith.  And, of course, people have altered scriptures to suit themselves.  One can still make sense of the Bible in the broad strokes, however.

Christians believe in a life in the hereafter, i.e., everlasting life.  This is, in fact, the "good news" or Gospel of the Bible.

However, one must be a believer to get it, and as atheists are not, they won't be getting it.  Thus, God DOES allow atheists to die.  And, stay dead.  That is the Christian thinking at least (in a simple form).

1 Timothy 2:4 [God] who wants all people to be saved and to come to a knowledge of the truth.

He wants you to be saved.  If he killed you right now, you wouldn't be saved.  By keeping you alive, he hopes you'll change and become a Christian.  Some atheists do just that.

Also, it appears you are unaware that the passage you cited was targeted to the ancient Israelites and them only, never any Gentiles as part of an agreement God made with them, and them only (Ex 19:3-8).  Christians are under the new covenant (NT) not the old one.

Because God, in his mercy, determined times for grace, and times for judgement. In times of grace, souls are allowed to make mistakes so they could learn the nature of the good and the nature of evil, and hopefully choose to turn away from evil. Times of grace eventually come to an end, and the judgement of God is executed.

The Bible says I take no delight in the death of the wicked but I want all to come to repentance and have eternal life.  God does not have to kill or harm a person that he considers wicked.  The person that is wicked or godless they'll harm themselves and take themselves out of existence God doesn't have to contribute to that the person that's godless or wicked will do it all by themselves.

Leaving behind the evidence that if you do not obey the rules that God sets down for you you'll make yourself and everybody around you sick weak and dead.

The coronavirus that we have right now in our face that's a prime example of what happens when you don't obey the written word of God when God says don't eat this or don't eat that God means it.

When you have food around that God says don't eat the whole world breaks out in a virus that kills hundreds of thousands of people. 

This isn't the punishment of God this is a self-punishment where a human being did what God said don't do!  And he reaped the natural consequences of his bad actions.

When you stick your hand inside of a fire and you get burned that's not God punishing you. That's you punishing yourself.

God has given mankind free will as to where you will spend all eternity. God offers you continuing life by obeying him.  The reverse is true if you don't obey God your life process will come to an end and when you come before God at judgment Day.

God will simply tell you well I'm sorry friend but you didn't build yourself a new body! 

And then to keep you from having further pain God will humanely remove your consciousness and dispose of you by cremation in the fire you will already be dead when you hit the fire.

God does not threaten to torture you if you don't obey him you will torture yourself and in the end God will take away your consciousness so that you can't torture yourself anymore. That's an act of kindness an act of Mercy not a punishment.

Cuz it's not real. 

(2 Peter 3:9) Jehovah is not slow concerning his promise, as some people consider slowness, but he is patient with you because he does not desire anyone to be destroyed but desires all to attain to repentance.

Romans 9

21 Does not the potter have the right to make out of the same lump of clay some pottery for special purposes and some for common use?

22 What if God, although choosing to show his wrath and make his power known, bore with great patience the objects of his wrath—prepared for destruction? 23 What if he did this to make the riches of his glory known to the objects of his mercy, whom he prepared in advance for glory— 24 even us, whom he also called, not only from the Jews but also from the Gentiles?
