The following is a summary of my most recent class in pursuit of my Master’s in Theology at Colorado Christian University.

For the purposes of this exercise, and not necessarily as a reflection of what you really believe, assume the stance of either an Arminian or a Calvinist. From the point of view of your chosen perspective, present and develop two ideas: (1) the one which is most convincing to you about the Calvinist or Arminian perspective and (2) the one with which you struggle the most regarding that perspective.
Concerning the differences between Calvinism and Arminianism, we must remember these schools of thought address two distinct issues: (1) free will and ability to choose one’s actions; and (2) election, or God’s choice, as to whom He saves. Calvinism and Arminianism both support the idea of the total depravity of man, to include an inability to choose how to behave. We cannot be saved by the Law. Rather, the Law merely informs us of our inability to “behave” ourselves into righteousness. Arminianism supports universal redemption (general atonement) and conditional election, whereas Calvinism believes in limited (definite) atonement and unconditional election. Calvin is best noted, of course, for adherence to “predestination.” After the Fall, man stood condemned before God. God chose and called “some” who would be saved.
Arminians believe God’s election depends on man’s free will because it is based on His foreknowledge. God does, in fact, see all time at the same time as noted by Grudem.  The apostle Peter said we are “chosen and destined by God the Father and sanctified by the Spirit for obedience to Jesus Christ and for sprinkling with his blood” (1 Pet. 1:2, RSV). Paul wrote, “For those whom he foreknew he also predestined to be conformed to the image of his Son, in order that he might be the first-born among many brethren” (Rom. 8:29). Arminians are clear that individuals must accept God’s calling to be saved. It is not a matter of being predestined or chosen “ahead of time.” It is interesting to note, however, that this doctrine (universal salvation) is not necessarily supported by Scripture. Since Jesus died for all, Arminians argue that all will be saved. First Corinthians 6:9-11 says the unrighteous will not inherit the kingdom of God; further, only those who are washed (sanctified, justified) by the blood of Jesus will be saved.
Taking the position of Calvinism, I would have to believe the “call” of God on our lives is resistible—we can reject Jesus or accept Him. However, once we accept Jesus as Messiah and Lord, the internal leading of the Holy Spirit is all-powerful, achieving God’s purpose in our lives and giving us a measure of grace to be able to choose. We can stand on the belief that God works out everything for good for those who love Him and are called according to His purpose (Rom. 8:28). We’re made “spiritually alive” with a new ability to see God’s plan for our redemption and the place of Jesus in that plan. This call is so wonderful and appealing that it becomes impossible to say no to God. This is not a violation of our free will because we didn’t really have it in the first place; our will was corrupted by original sin. Martin Luther believed even the most excellent of men—endowed with the Law, righteousness, wisdom, and all virtues—is nonetheless ungodly and unrighteous. Due to the innate nature of sin, man cannot consistently choose to act righteously, if at all. 
Paul gave the example that many Jews were without faith who were most wise, most religious, and most upright. He said they had a “zeal” for God yet were transgressors of the Law. He wrote in Romans 3:9-10 that the Jew was no better than the Gentile; both are under the power of sin. No one is righteous on their own. This fits well with Paul’s remark that we do not wrestle with flesh and blood, but with powers and principalities; rulers of the darkness of this world (Eph. 6:12). Because we all are Adam, we need salvation. Adam’s offense comes to us not by imitation, nor necessarily by anything we do (although we do sin, sometimes habitually); rather, we receive our sin nature by birth. Luther believed original sin “does not allow ‘free-will’ any power at all except to sin and incur condemnation.”  Therefore, he rejected the notion of free will. He believed this conclusion is well supported by Scripture, especially in the writings of John and Paul.
Grudem quotes Peter, who called Jesus, “a stone that will make men stumble, a rock that will make them fall; for they stumble because they disobey the word, as they were destined to do” (1 Pet. 2:8, emphasis added). Peter says in verse 10, “Once you were no people but now you are God’s people; once you had not received mercy but now you have received mercy.” Grudem says in a footnote related to verse 8, “The ‘destining’ in this verse is best taken to refer to both the stumbling and the disobedience. It is incorrect to say that God only destined the fact that those who disobey would stumble.”  Grudem notes that Calvin gives some room for man’s “free” acts and choices. Calvin admitted, however, that this statement is a bit confusing, causing him to avoid using it. Instead, man has “this sort of free decision, not because he has free choice equally of good and evil, but because he acts wickedly by will, not by compulsion.” 
For me, this idea of “will” can mean only one thing: man acts wickedly by deciding to reject the Light of Christ and remain in darkness. He is compelled by his sin nature to act the only way he can—in an ungodly and unrighteous manner. Admittedly, some men choose to act justly or “God-like” at times, but no man is capable of decidedly obeying the Law and acting righteously in a consistent manner. He is not compelled or tempted to do so by God. James said, “When tempted, no one should say, “God is tempting me.” For God cannot be tempted by evil, nor does he tempt anyone; but each person is tempted when they are dragged away by their own evil desire and enticed” (James 1:13-14, NIV, emphasis added).
Grudem notes that God has made us responsible for our actions, reminding us that our actions have real and eternal consequences. He notes that Adam blamed Eve for his own disobedience, saying, “The woman whom thou gavest to be with me, she gave me fruit of the tree, and I ate” (Gen. 3:12). Scripture, as Grudem notes, never blames God for sin. Regardless, He accomplishes all things (no matter their impetus) according to the counsel of His will (Eph. 1:11). In the case of Job, God pulled back and allowed Satan to attack Job in any manner He chose (including wiping out his livestock, killing his wife and children), but He would not allow the devil to kill Job. This type of issue gives me pause. It is easy, at least in my human intellectual capacity, to think God willed (therefore, caused) evil on Job’s animals and his family. Innocent people died for God’s point to be made. However, when I consider the horror and evil inflicted upon Jesus during the last twelve hours of His life (what we consider the “passion”), and when I play it out to the end, seeing that mankind could only be redeemed through the shedding of the blood of Jesus, I have an easier time understanding what is meant by God using whatever happens to accomplish His will.
Grudem says, “In response to the claim that choices ordained by God cannot be real choices, it must be said that this is simply an assumption based once again on human experience and intuition, not on specific texts of Scripture.”  Note that Grudem uses the term “ordained by God,” and does not say God performed the evil act itself. This speaks of the means through which He achieves His intended result. We are fearfully and wonderfully made (Psalm 139:14). We’re made in such a way, however, that God ordains all we do. The Calvinist would endorse the theory that God does not sin but brings about His will through secondary causes, including the immorality of others. We should accept that whatever God ordains is within His purview and His authority.
Calvin distinguishes between “necessity” and “compulsion.” He notes that unbelievers necessarily sin. Scripture supports this, as does Martin Luther. There is, however, no “Godly compulsion” to sin. There is simply God’s ability to use whatever happens to further His will and promote His glory. What I find most difficult to grasp regarding Calvinism is the idea that God “predetermined” who will be saved and who will not. Perhaps this is a gross misinterpretation of “predeterminism.” The concept that, before the foundation of the world, God predestined a plan of redemption is about the plan and not a prior decision who He will accept and who He will reject. In addition, because God sees the past, the present, and the future all at once, He already knows who will be saved. The responsibility still remains with each individual to either accept or reject the sacrificial death of Jesus as the Lamb who takes away the sin of the world.
