As the bird with a broken wing is “free” to fly but not able, so the natural man is free to come to God but not able. How can he repent of his sin when he loves it? How can he come to God when he hates Him? This is the inability of the will under which man labors.
Jesus said, “And this is the judgment, that light is come into the world, and men loved the darkness rather than the light; for their works were evil,” John 3 :19; and again, “Ye will not come to me, that ye may have life,” John 5:40. Man’s ruin lies mainly in his own perverse will. He cannot come because he will not. Help enough is provided if he were only willing to accept it.
Paul tells us, “The carnal mind is enmity against God; for it is not subject to the law of God, neither indeed can it be. So they that are in the flesh cannot please God:” Romans 8:7.
To assume that because man has ability to love he therefore has ability to love God, is about as wise as to assume that since water has the ability to flow, it therefore has the ability to flow up hill; or to reason that because a man has power to cast himself from the top of a precipice to the bottom, he therefore has equal power to transport himself from the bottom to the top.” ~ Loraine Boettner (1901-1990). Excerpt from Loraine Boettner’s classic book, The Reformed Doctrine of Predestination.
