From a believer's point of view, especially a Reformed Christian believer's point of view, the main theme of the bible boils down essentially to this:
God placed Adam and Eve on Earth, in a beautiful place; but a testing ground. Adam and Eve had the full freedom to do anything they chose, but for 2 things. Don't eat from the tree of life, and don't eat from the tree of knowledge. God watched to see if Adam and Eve could live with 99% freedom. The answer is no. Adam and Eve (and as ones who represent mankind perfectly, all of us) could not be satisfied unless they could do anything they wanted. And so it goes... they ate from the tree, commited cosmic treason, and plunged all of creation into sin.
Later, another Adam--the perfect Adam--arrived on the scene; God incarnate; Jesus the Christ. Christ, in a new Covenant with mankind, paid the price for our sins, died on the cross, and offered us a way out.
And Christians since that time, now, and in the future, are reborn and in us, the relationship God intended is reestablished. Christ bought us and paid for us. Just as in the old days a slave was bought and paid for and then obligated to serve its new master; so then are we, the Christian believers. We were purchased for the ultimate price, as slaves to Christ, and we are completely happy with the arrangement. We don't have utter and complete autonomy, nor do we desire it.
The unbelieving don't understand how someone could be a slave, without 100% autonomy, and be satisified. Not meant as demeaning, but, just like Satan in the garden, the unbelieving ceaselessly strive to make us understand that we could be happier, we just don't know it. If only we are freed from our Master to enjoy the benefit of full autonomy, then we would understand how much better it is to live that way.
But I, as one who transformed relatively late in life, have seen the situation from both sides. And I can tell you unequivocally, without any doubt whatsoever, that life is infinitely better as a slave to Christ, with 99% freedom and the assurance of immortality. The alternative, like a shiny red apple, may seem appealling; but we as believers know that the benefits full autonomy has to offer are fleeting and ultimately lead to death.
Every one who is seriously involved in the pursuit of science becomes convinced that a spirit is manifest in the laws of the Universe-a spirit vastly superior to that of man. - Albert Einstein
