Original Sin

What is original sin?
The original sin, was actually effectuated in heaven when Satan chose to steal God's mojo and persuade Eve to worship him instead of God. However, some would consider Adam and Eve's sin as the original sin, since it was the root of physical suffering.Why is it a necessary belief to the Chritian experience and is it, like other sins, washed away by the blood of Jesus?
If one is to embrace the Christian scriptures then the typical arrangement is to acknowledge the original prophesy given by God following the fall of Adam and Eve.Jesus did wash away the original sin, however the recovery will not take effect until this system has concluded or expired. Since God told Satan that he would allow humans to exist independently(just as Satan promised) and demonstrate the futility of his words. It would also allow everyone the opportunity to choose.Further, if it is washed away by the blood of Jesus, why is it brought up in the first place?
There is a great deal of knowledge in the origin of mankind and knowledge is the key to happiness.Once a child is old enough to ask Jesus for forgiveness wouldn't the original sin then be washed away?
Since God has demonstrated he is a God of balance, it should come as no surprise that He employed Jesus to pay ransom for Adam and Eve's actions. Through there actions. Adam and Eve lost tainted perfection and brought death and suffering upon all of there offspring. The only way to recovery from this, was to somehow regain or give back the elements which were lost. In this case Jesus perfect life on earth was equal to that of Adam and Eve and therefor worthy of a ransom for their sins.While this system runs its course, we are all entitled to receive forgiveness under God in his name. The permanent redemption will be achieved when God's plan for a perfect world is restored and Jesus hands over the rulership of earth back to God.
