Y I'm not a Calvinist....but I do know how a Calvinistic Methodist would have answered the question.
Excuse me for butting in on this conversation .... BUT how a Calvinist Methodist, or Calvinist Baptist, or Roman Catholic, or Mennonite, or Lutheran, or evangelical. Whatever would have answered your question pales in light of what and how we should respond to any question about our salvation and our relationship with Jesus.
It is not the doctrine that saves us. It is not the doctrine that covers our sin. It is not the doctrine that promises and assures eternal life. It is not the doctrine that we are faithful to and lives to please. It is not the doctrine that pleases God.
Paul says this about religion in Romans 1:17-18,
"For I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes: first to the Jew, then to the Gentile. For in the gospel, the righteousness of God is revealed—a righteousness that is by faith from first to last, just as it is written: “The righteous will live by faith.”
He then goes on to describe those who were and who will succumb to the things of the world, the things devised from man's intellectual understandings and warped approach to worship and serve a Holy God in Romans 1:18-32,
"The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, since what may be known about God is plain to them, because God has made it plain to them. For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. Although they claimed to be wise, they became fools and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles.
Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen.
Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error.
Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips, slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; they have no understanding, no fidelity, no love, no mercy. Although they know God’s righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them.
It is clear to me that if one is expected to respond to our questions about salvation and our relationship with Him, it should not be based upon one doctrine OVER another, but on what happened on the cross, and how Jesus has changed our life. Is changing our life. And where we will be spending eternity.
I know this will set off a round of discussion, because I have trampled upon the vaunted and lofty expectation that men have of their precious doctrines. And while it is necessary that the church follows doctrines, it is when man places more emphasis upon the doctrines they have written then the words of Scripture, that those man-made doctrines become IDOLS to us, and we then begin to slide further and further from the simplicity of the work of the cross, HIs blood that was shed to cover our sins, and how the cross brings us a new relationship rather than a religion. When relationship turns into religious doctrines and things we must say and do to remain faithful not to God but to the man-made doctrines, then those doctrines become an idol whom we follow, and Paul tells us that we become "fools" and regress into sinfulness, because it is not the doctrines of man, but rather the work of Christ on the cross that changes us, and teaches us, and leads us. Or allegiance and responses must not be to doctrines, but to Christ.
The scripture doesn't say that they shall know us by our doctrines, but by our love. And sorry to say, doctrines squeeze the love out of us, and turn us into the very things God sent HIs Son to put an end to!
Something about Idols, and warnings against making and following Idols. It is my belief that when we hold certain doctrines above the simplicity of the Gospel message, idols are born, and they only grow from that day on:
