Gordon H. Clark, “God’s Hammer: The Bible and its Critics” pg.20-23:
When Adam fell, the human race became, not stupid so that the truth was hard to understand, but inimical, to the acceptance of the truth. Men did not like to retain God in their knowledge and changed the truth of God into a lie, for the carnal mind is enmity against God. Hence the preaching of the cross is to them that perish foolishness, for the natural man receives not the things of the Spirit of God because they are spiritually discerned. In order to accept the Gospel, therefore, it is necessary to be born again. The abnormal, depraved intellect must be remade by the Holy Spirit; the enemy must be made a friend. This is the work of regeneration, and the heart of stone can be taken away and a heart of flesh can be given only by God himself. Resurrecting the man who is dead in sin and giving him a new life, far from being a human achievement, requires nothing less then almighty power.
It is therefore impossible by argument or preaching alone to cause anyone to believe the Bible. Only God can cause such belief. At the same time, this does not mean that argument is useless. Peter tells us, “always be ready to give a defense to everyone who asks you a reason for the hope that is in you.” This was the constant practice of the apostles. Stephen disputed with the Libertines; the Jerusalem council disputed; in Ephesus Paul disputed three months in the synagogue and then continued disputing in the school of Tyrannus. (Acts 6:9; 15:7; 19:8,9: compare Acts 17:2; 18:4, 19; 24:25). Anyone who is unwilling to argue, dispute, and reason is disloyal to his Christian duty. Continue reading
