So now I'd like to touch on the matter of Regeneration, as it pertains to "in Christ." Calvinism teaches that not everyone can be saved, but only those to whom God elects to give an Irresistible Grace. So what exactly is that? It's also referred to as an "effectual calling." It's said that in the foreordained time, God makes an "elect" person preemptively Born Again, regenerated and with a new heart, and thus naturally comes to Christ, as a consequence of such a regeneration. Obviously, Arminians such as myself, absolutely insist that no one outside of being "in Christ" is entitled to such a new birth and regeneration. Arminians argue that only when a person hears and believes in the Gospel, and is sealed in Christ by the Holy Spirit, as per Ephesians 1:13, does he then receive regeneration, the new birth and a holy calling (i.e. vocation in Christ). That's why I'd like to highlight a particular statement from James White, concerning Regeneration & In Christ:
Calvinist, James White, writes: “When the time comes in God’s sovereign providence to bring to spiritual life each of those for whom Christ died, the Spirit of God will not only effectively accomplish that work of regeneration but that new creature in Christ will, unfailingly, believe in Jesus Christ (‘all that the Father gives Me will come to Me’). Hence, we are not saved ‘without’ faith, but at the same time, Christ’s atonement is not rendered useless and vain without the addition of libertarian free will.” (Debating Calvinism, p.191, emphasis mine)
White believes that “the elect” are already in Christ, despite being unbelievers. Why? Because he needs what is reserved in Christ alone, namely, Regeneration, to be given to unbelievers in order to become believers. He correctly recognizes that regeneration is alone reserved in Christ (2nd Corinthians 5:17), and that with such regeneration, comes the new birth of being made Born Again with a new heart and a new spirit. The new heart is what Calvinism needs for the decision for Christ to be rendered irresistible, as in Irresistible Grace. However, and this is where Calvinism gets in trouble, Calvinism requires that regeneration (born again, new birth, new heart) be made preemptive (given to unbelievers) in order to overcome Total Inability, and since regeneration alone comes in Christ, being in Christ, therefore, must also be rendered preemptive as well. But it’s not, since being in Christ also carries with it, Redemption (Romans 8:1), and Redemption requires faith in Christ (John 3:18), and faith precedes the sealing in Christ. (Ephesians 1:13) Therefore, when in Christ is shifted forward into a preemptive state, you can see how much damage it does to these other verses. So the answer to the question of “When do you become in Christ?” is after believing in the Gospel, which we already knew from Ephesians 1:13. (For more details on this point, see also: http://www.examiningcalvinism.com/files/Articles/when.html)
How can a condemned and judged old creature in Adam (John 3:18), simultaneously live in Christ? Answer? They cannot. You must spiritually die in Adam and become raised to new life in Christ. When we are crucified with Christ, according to Galatians 2:20, William MacDonald explains: “It means the end of me as a child of Adam, as a man under the condemnation of the law, as my old, unregenerate self.” (Believer’s Bible Commentary, p.1180)
Being a "new creature" is the mark of identification of being in Christ. Being the "old creature" is the mark of identification of being outside of the body Christ, namely, in Adam. Since being in Adam and being in Christ are Mutually Exclusive, you cannot simultaneously be in both. Those who are in Adam are judged. (John 3:18). Those who are in Christ are redeemed, and are free from condemnation. (Romans 8:1) Hence, Calvinism is a non-starter, unless there is such a thing as a regenerate, redeemed unbeliever who thus, by being preemptively placed in Christ, will now unfailingly come to believe in Christ.
