Calvinism is a diverse and complex theological system. When one attempts a study of the system, it doesn’t take long to discover that there are many side roads and many twists and turns in the path to understanding. The problem is complicated by those who hold to the system because there is no single view that all Calvinists accept.
Sin? It’s out of date, old fashioned, and to consider any behavior, attitude, or action sinful is just not acceptable to the dullards who promote themselves to be the wise men of today.
The Calvinists will tend to emphasize the role of “God” in loving the world and giving the Son. The Arminians will tend to stress the word “whosoever” as indicating human freedom and the human decision-making process in salvation.
If I shoot a man without cause, that action would be wrong. But if a police officer shoots a man with cause, then the action would be regarded as justified. The same action is judged differently when it is carried out by different actors in different circumstances.
It would seem that to submit humbly to Christ’s teaching would require a willful act on the part of the believer rather than a forced submission. Once again I would argue, the only part in salvation that man can play, and must play, is that of a beggar who in response to God’s calling cries out like the Publican, “God be merciful to me a sinner.”
