Wondering One, the reason I am willing to confront on this issue is that the end result of Calvinism is "too bad for most of the world, God didn't REALLY love you enough to send His son for you; it was only for us chosen who were predestined from before birth."
Calvinism presents hopelessness to the rest. They use the word 'choice,' but those others really have no choice because God did not select them from the beginning.
To me, this denies God's essential character of love and justice and mercy, altogether. Love means you care for someone's welfare more than your own. John 3:16 says God cared in this way enough to send His Son, and Revelation 13:8 says the sacrifice was a reality from the foundation of the world. John 3:16 says 'whoever' or 'whomsoever' (or whatever word your preferred translation uses -- they all indicate that 'whoever' is not a 'preselected few') believes will inherit eternal life.
It is absolutely essential that all men know that they are free to choose Christ, despite having a sin nature. His very mission is to rescue a man from himself, and give him a new nature.
It is not just, it is not merciful, and it most certainly is not love to condemn the vast majority of people created to hell by virtue of their sin natures and only select a few to be saved. This gives the appearance of randomness to us and denies everything He has created within us which declares the meanings of justice and mercy.
And so, because I feel the very character of God is at stake, I will confront Calvinism whenever possible. They claim that those who don't agree with them deny the sovereignty of God. Baloney. He is more sovereign than that doctrine will allow, for He is sovereign enough to give us the choice and still be in complete control. It's like a parent giving a choice to a small child -- the parent never loses control no matter which choice the child makes.
In God's case He has known the end from the beginning, so He does know what our choices will be, but that does not mean He has chosen for us. The command to "Choose this day whom you will serve" did not end with the Israelites entry into the Promised Land. It has rung down through the ages since Adam and Eve. And so even the writer to the Hebrews literally begs his readers, "Today, if you hear his voice, do not harden your hearts as you did in the rebellion". And we see here also that it is not sin which condemned them, or us, but unbelief: "So we see that they were not able to enter because of their unbelief." (From Hebrews 3)
Chapter 4 begins with the following:
Therefore, since the promise of entering his rest still stands, let us be careful that none of you be found to have fallen short of it. For we also have had the gospel preached to us, just as they did; but the message they heard was of no value to them, because those who heard did not combine it with faith.
That does not sound to me like only those God has already chosen will be allowed in. Does it sound like it to you?
And yet that is what the Calvinists here are saying -- that despite all the pleas and arguments presented throughout the entire Bible, only those pre-selected by God will ever be rescued anyway.
I cannot leave people here with that kind of fatalistic hopelessness.
And so I take the time to respond as often as I can.
