OK. Though I am still reluctant to believe you are not attempting another of your ruses here goes.
There are centuries of discussion on this subject. They range in scope from those who believe that God knows the future and the past so that the actions of individuals are predetermined, so to speak, to those who believe that God allows the world to progress as its inhabitants wish only pausing to intervene when it suits His purposes. There are those who believe that all of God's work was finished with Jesus and that from then on we are free to win or lose based upon our own free decisions.
MY belief is that most Christians believe that they are free to make bad or good decisions. We believe that we start off with the tendency to follow our baser instincts and that our religious convictions temper those instincts. Because we believe that we have and will always tend to violate the perfect vision for human behavior that God has presented us with and that we must ultimately rely on the fact that God knows we are weak that he will make allowances for our weakness. In other words we fear His judgment but we hope and rely on the mercy which He has promised to us.
We also believe (and most religious texts teach) that not all people are called to the same standard. Some, like a Franciscan Friar friend of mine hold themselves to a very high standard indeed. He has taken a vow of poverty, chastity and obedience to the rule of St. Benedict and his superiors and takes a very literal and comprehensive view of those rules. For example he leads a very austere life and as a reminder to himself that there are homeless in need of his (our) help, sleeps on the floor without a mattress to be in solidarity with them.
So the question is, "Is this necessary for him to achieve God's favor and reach eternal life in unity with Him?" I would say that this is at the very essence of free will for me. My friend does this because he believes that God calls him to do it but that in the end it is his own decision based upon his own free will. I believe that even absent these extraordinary actions my friend has to rely on God's mercy just as much as I do. And my efforts to live a Christian life are insignificant compared to his.
As I exercise my free-will am I aware that I am breaking the rules that God has set as the ideal standard? Of course. Do I do it deliberately? Of course. How could I claim otherwise. I could fry for all eternity just for coveting my neighbor's ass, so to speak. So knowing that I, as all humans are, weak by God's standards, I and my sainted friend both rely on God's mercy for both our hope and our inspiration.
So is this slavery? Not at all. It is the very opposite. It is, if you really think about it, for a believer, the assertion that we have freedom to behave as we please in the very face of the Creator and Ruler of the universe. God is not my master. Think about that. Not my master.
In one of the most important verses in the Bible, Jesus says:
"Pray then like this: “Our Father in heaven, hallowed be your name.
Father. Not master.
Then Paul tells us:
So you have not received a spirit that makes you fearful slaves. Instead, you received God's Spirit when he adopted you as his own children. Now we call him, "Abba, Father."
A child is not enslaved by his/her father. Taught, chastened, admonished, loved, but not enslaved.
So. Sometimes institutions claiming to hold the proverbial Keys to the Kingdom wish to control the behavior of their congregations. We see this is the history of Churches. We see it in writ large in much of Islam today. But speaking for Christianity (with apologies for my arrogance) we do not see this as necessary or even preferable for our salvation. As much as some church leaders might wish to force-feed us righteousness, in the end we all rely solely on the mercy of God. And we need no interlocutor between us individual and Him. That is a very naïve (on my part I am sure) view of the most commonly held view.
