After posting on Pater15’s thread elsewhere, I said something that he responded to with the following:
Many here (including me) would ask you to explain what you mean by “earning the right to go to heaven.” Salvation is a free gift, so it’s the claim that we somehow earn it that would be problematic.
I referred specifically to the fact that salvation from sin and eternal life are not the same thing, but I do realize that false Calvinistic doctrine has crept into the mainline church, so I will explain. Calvinism treats salvation from sin and eternal life as one and the same thing, when they are not, and this is why they claim that all you need to do in order to make it to the consummation of eternal life in heaven, is to simply believe in Jesus.
Salvation and eternal life are treated in Scripture as two completely different, but intimately related, doctrines. Part of the confusion comes into play because many times Paul uses these terms as metonyms for one another, and so throws people off who do not recognize linguistic genres in Scripture. Furthermore, salvation from sin and eternal life are different in their nature’s and purposes; salvation from sin is a one time, singular historical event in the life of a believer, just like if you were saved from drowning at 16, we do not keep saying you are saved from drowning, we say you are alive.
In direct contradistinction, eternal life in Scripture is portrayed as a conditional state of being in some passages, while in other passages it is covenant terminology for one being in covenant relationship with God (such as John 17:3); and in other passages, eternal life is addressed as making it to heaven where we will have eternal life codified.
This is why one can get saved in the past and still end up in eternal fire when they die, because contrary to false teachings and doctrines, salvation is not for the purpose of taking you to heaven, and heaven is not guaranteed just because one gets saved. This is why John says:
John 3:36*
Whoever believes in the Son has eternal life, but whoever does not obey the Son shall never see that life: because the wrath of God continues to remain upon him.
The purpose of salvation from sin is to qualify us to enter into God’s very presence so that we can engage Him in personal relationship; it is that relationship that takes a man into heaven, not salvation. Salvation from sin is based upon the same laws of atonement that God gave to Moses, the only difference is that Christ is our sacrifice and we do not need to sacrifice an animal every time we sin.
Blessings.
