Baptist pastor Walter Chantry has a great little essay on The Myth of the Free Will. He outlines the subject as:
I. The Myth of Circumstantial Freedom
II. The Myth of Ethical Freedom
II. The Myth of Spiritual Freedom
I like this section of point II especially, though it is all good.
But freedom of the will is cited as an important factor in making MORAL decisions. Man's will is said to be free to choose between good and evil. But again we must ask, from what is it free? And what is man's will free to choose?
The will of man is his power to choose between alternatives. Your will does decide your actions from a number of options. You have the faculty to direct your own thoughts, words, and deeds. Your decisions are not formed by an outside force, but from within yourself. No man is compelled to act contrary to his will, nor forced to say what he does not wish. Your will guides your actions.
Yet this does not mean that the power to decide is free from all influence. You make choices based on your understanding, your feelings, your likes and dislikes, and your appetites. In other words, your will is not free from yourself!
Your choices are determined by your own basic character. The will is not independent of your nature, but the slave of it. Your choices do not shape your character, but your character guides your choices. The will is quite partial to what you know, feel, love, and desire. You always choose on the basis of your disposition, according to the condition of your heart.
It is just for this reason that your will is NOT free to do good. Your will is the servant of your heart, and your heart is evil. “And God saw that the wickedness of man was great in the earth, and that EVERY imagination of the thoughts of his heart was ONLY evil CONTINUALLY“ (Gen 6:5). “There is NONE that doeth good, no, not one” (Rom 3:12). No power forces man to sin contrary to his will, but the descendants of Adam are so evil that they always choose the evil.
Your decisions are molded by your understanding, and the Bible says of all men, “And their foolish heart was darkened” (Rom 1:21). Man can only be righteous when he desires to have fellowship with God, but, “There is NONE that seeketh after God” (Rom 3:11). Your appetites crave sin, and thus you cannot choose God. To choose good is contrary to human nature. If you chose to obey God, it would be the result of external compulsion. But you are free to choose, and hence your choice is enslaved to your own evil nature.
