The short answer: you’re here in the flesh to choose either God or Satan. Most of the world go with Satan.
Also, no one has stopped living yet. Yes, the flesh-body dies; however, only God can kill your soul.
Matthew 10:28 And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.
This is important that you understand that there is only one person that can kill both your body and the soul, and that person is the Almighty God Himself. He created both your body and your soul, and just as He created both, He also can destroy both body and soul. This also documents just where it is that the wicked souls will be destroyed.
So the only thing that the true Christian has to fear, is to commit the unforgivable sin, and that can only be committed when you are delivered up to the synagogues of Satan, and you refuse to allow the Holy Spirit to speak through you. As you do your witnessing the Holy Spirit will protect you all the way. Only God's elect will be delivered up, those bound in traditions need not fear of sinning this sin, for they will not be turned over to Satan because they will be there already.
Ecclesiastes 12:6-7
6 Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern.
The "cistern" is the clay flesh body that our soul lives in. The cistern is built to hold the water or life that is within the flesh body, but once that bowl is broken the water or life leaks out of it, just as water leaks out of this flesh body. The "silver cord" is what holds your soul and the spirit together with the flesh body. We can call it the process of thought, which is the intellect of the mind, or soul.
When one is brain dead, there is no electrical impulse within the brain, and mankind is considered dead, even though the physical body may still be pumping blood. Life support systems are generally discontinued in most cases.
When that silver cord parts and the heavenly Father allows it to happen, and this flesh body becomes biologically dead, the very inner man departs for this physical body and returns to the Father. This decaying body will never be used again, ever. For the soul has entered into its new incorruptible body.
7 Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
Then when? After the silver cord breaks, the mind is brain dead, and the body loses its life. Then shall the body "dust" return to the earth as it was, before it was formed into food, and entered your mouth as food to make your flesh body healthy.
The spirit is the intellect of the soul, that gives the soul its identity. This is not complicated. When the body dies and goes to the grave, the physical body will never have a use again, for the soul has returned to the Father, to God who created it in the first place. Because this is a promise of God, it should be what all Christians look forward to all the days of their lives. That is the day that we will be with the Father and Jesus Christ is heaven, not at some distant time in the future.
When a man gets to the point of not being able to understand this promise that at death the soul goes immediately to be with the Father, then he forms his religious, man-made ideas, and sidesteps what God's Word teaches. Friend, it takes only a short time for the body to decay, and there is nobody there to resurrect. The body returns to the dirt that it is made of, and the soul departs from that body never to return to it.
God creates the flesh body for your soul to occupy, and He places your spirit within your soul. That is what gives your soul its identity. Then just as God gave it for a brief time, He will take your soul back to Himself, when the flesh body stops having a life.
I suggest that you find a good bible teacher.
