If God created us with the capacity to love and thereby giving us the ability of free will, the ability too choose. He has given us the choise to be a decent human beings but also the choise to commit sin, which he does not like and that is understandabe but he allows it. With my ability to choose why can I not choose to leave this place, my body, this life, and simply sit beside him and watch the world with him?
This is from an SDA perspective.
That depends on what your belief is of what happens after death. Based on the Bible, when you die, you are unconcious and await the resurrection.
There is Biblical support that supports the idea of death sleep: The dead do not know anything:
For the living know that they will die; But the dead know nothing, And they have no more reward, For the memory of them is forgotten.
The dead cannot do anything:
Whatever your hand finds to do, do it with all your might; for there is no activity or planning or knowledge or wisdom in Sheol where you are going.
The dead cannot praise God, or hope in His faithfulness:
For the dead cannot praise you; they cannot raise their voices in praise. Those who go down to the grave can no longer hope in your faithfulness.
There is no mention of God by the dead:
For there is no mention of You in death; In Sheol who will give You thanks?
Jesus mentions that Lazarus, who was at the time dead, was simply sleeping:
11 These things He said, and after that He said to them, “Our friend Lazarus sleeps, but I go that I may wake him up.”
12 Then His disciples said, “Lord, if he sleeps he will get well.” 13 However, Jesus spoke of his death, but they thought that He was speaking about taking rest in sleep.
14 Then Jesus said to them plainly, “Lazarus is dead. 15 And I am glad for your sakes that I was not there, that you may believe. Nevertheless let us go to him.”
Paul says that those who sleep, or died in Christ, simply wait for His return and their resurrection.
13 But I do not want you to be ignorant, brethren, concerning those who have fallen asleep, lest you sorrow as others who have no hope. 14 For if we believe that Jesus died and rose again, even so God will bring with Him those who sleep in Jesus.[b]
15 For this we say to you by the word of the Lord, that we who are alive and remain until the coming of the Lord will by no means precede those who are asleep. 16 For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. 17 Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord. 18 Therefore comfort one another with these words.
1 Thessalonians 4:13-18
From this perspective, you don't watch the world, as mainstream Christianity would have you believe. It is unbiblical and was adopted from Greek Philosophy.
