It is inherent in the nature of man that his will must be free. Made in the image of God who is completely free, man must enjoy a measure of freedom. And God respects this freedom. God once saw everything that He had made, and behold, it was very good. To find fault with the smallest thing God has made is to find fault with its Maker.
Sin excepted, there is nothing in human nature to apologize for.
So highly does God regard His handiwork that He will not for any reason violate it. He will take nine steps toward us but He will not take the tenth. He will incline us to repent, but He cannot do our repenting for us. It is of the essence of repentance that it can only be done by the one who committed the act to be repented of. God can wait on the sinning man, He can withhold judgment, He can exercise long suffering to the point where He appears lax in His judicial administration - but He cannot force a man to repent.
