Do not confuse the process with the result. Salvation is not just a different way of thinking or believing. It is not just a vertical relationship mankind - God. It is also a new mission and a new axis. Christianity (as was Judaism) was all about both a vertical relationship with God thru Christ but just as importantly there is a horizontal axis. If you hate your neighbor then you hate God. If you love God you will love your neighbor as yourself. Paul is clear, love trumps faith. Love can only be transacted on the horizontal - earthly - axis. Jesus says if you love me you will keep my commandments and God will love you too. Jesus commandments have to do with your life, your heart and your mission. So we cannot stop our definition of salvation at square 1 - real faith. There is way more required of us than our Christian birth just as we expect and require more of our newborns.
Ephesians 1:13
13 In Him you also trusted, after you heard the word of truth, the gospel of your salvation; in whom also, having believed, you were sealed with the Holy Spirit of promise,
Key word is AFTER... you heard the word of truth, trusted, and believed.
...You were sealed.
Step 1: Heard, trusted, believed
Step 2: Sealed by Holy spirit
That's one of the ends of Calvinism
Here's another verse
John 1:12
12 But as many as received Him, to them He gave the [a]right to become children of God, to those who believe in His name: who were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
Keyword is become. These non-children of God were given the right to become children of God... to as many as RECEIVED and BELIEVE on his name. This is obvious to me , but if Calvinism were true, then it should read in reverse. It's based off as many RECEIVED and BELIEVED, not based off as many have been regenerated.
These have been given the right to become children of God. And of course man has no power or ability to become children of God. So, the next verse reads "who were born out of the will of God, not of man's will"
Read these carefully, and think outside a little of your Calvinist box and you'll see it.
Issue is Calvinists are indoctrinated heavily and have invested so much... I think it's hard for them to see
