Going to Heaven: God's Plan and Every Good Man's Destiny?

For centuries Christians everywhere have believed that if you are good and go to Church, then when you die you will be rewarded with eternal life in heaven. But, is that really what God has lined up for us? Why don't we look into the Bible and see what our creator has to say on the subject.

Look at God's original purpose.

If you read Genesis over pretty well (look closely at Genesis 2:15) there is no mention or even a hint that God had promised Adam he would live in heaven at any point. His purpose was to live on the earth and cultivate the garden Jehovah had created. Yes, things changed after he sinned but, does this mean Gods plans changed?

"God is not a man that he should tell lies,
Neither a son of mankind that he should feel regret.
Has he himself said it and will he not do it,
And has he spoken and will he not carry it out?"
-Numbers 23:19 

"so my word that goes forth from my mouth will prove to be. It will not return to me without results, but it will certainly do that in which I have delighted, and it will have certain success in that for which I have sent it" -Isaiah 55:11

These scriptures show that God's plans do not fail. If he starts to do something it will have "certain success". 

Death - - part of Gods plan?

Is it a fair assumption to say that God planned for humans to live on earth for a certain number of years, die, and then ascend to heaven? An examination of the scriptures shows results to the contrary.

"That is why, just as through one man sin entered into the world and death through sin, and thus death spread to all men because they had all sinned—" -Romans 5:12

"For the wages sin pays is death" -Romans 6:23

This is clear evidence that only after Adam sinned did death enter into the picture. Humans were meant to live forever on the earth doing the same job Adam had been assigned.

Do any go to heaven?
