We are saved (salvation) by grace (unmerited and unearned favor from God) through faith (there can be no salvation without faith and where does that faith come from?) faith comes from God (that's what the Bible states)
Calvinism teaches that life precedes faith and it is that life which gives a person the ability to believe the gospel. However, the Apostle John makes it plain that "life" comes as a result of believing and nor prior to believing:
"Jesus performed many other signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Messiah, the Son of God, and that by believing you may have life in his name" (Jn.20:30-31).
We can see that same truth here:
" And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses" (Col.2:13).
No one can be made TOGETHER with Christ while they remain defiled in their sins and no one has their sins forgiven until they believe:
"All the prophets testify about him that everyone who believes in him receives forgiveness of sins through his name" (Acts 10:43).
The following verse shows our position in Christ when we are made alive together with us:
"And this is the record, that God hath given to us eternal life, and this life is in his Son" (1 Jn.5:11).
That life which we are made alive "together" with Him is described as "eternal life." John Calvin says the following about 1 John 5:11:
"But the Apostle, that he might keep us together in Christ, again repeats that life is found in him; as though he had said, that no other way of obtaining life has been appointed for us by God the Father. And the Apostle, indeed, briefly includes here three things: that we are all given up to death until God in his gratuitous favor restores us to life; for he plainly declares that life is a gift from God: and hence also it follows that we are destitute of it, and that it cannot be acquired by merits; secondly, he teaches us that this life is conferred on us by the gospel, because there the goodness and the paternal love of God is made known to us; lastly, he says that we cannot otherwise become partakers of this life than by believing in Christ" (John Calvin, Commentary on 1 John 5:11).
