In Issue # 20 of Case Magazine in 2009 William Lane Craig offered an interesting discussion about the place of Christian Apologetics. This is an extract from the article.
Romans 8.14-16; 1 John 2.27; 5.6-10), so that argument and evidence become unnecessary. Further, the Christian evidentialist faces other severe difficulties:
(1) He would deny the right to Christian faith to all who lack the ability, time, or opportunity to understand and assess the arguments and evidence. This consequence would no doubt consign untold millions of people who are Christians to unbelief.
(2) Those who have been presented with more cogent arguments against Christian theism than for it would have a just excuse before God for their unbelief. But Scripture says that all men are without excuse for not responding to the revelation they have (Romans 1:21).
(3) This view creates a sort of intellectual elite, a priesthood of philosophers and historians, who will dictate to the masses of humanity whether or not it is rational for them to believe in the gospel. But surely faith is available to everyone who, in response to the Spirit’s drawing, calls upon the name of the Lord.
(4) Faith is subjected to the vagaries of human reason and the shifting sands of evidence, making Christian faith rational in one generation and irrational in the next. But the witness of the Spirit makes every generation contemporaneous with Christ and thus secures a firm basis for faith.
So I do not, in fact, think that apologetics is necessary in order for Christian belief to be warranted. But it does not follow that Christian apologetics is therefore useless or of no benefit in warranting Christian faith. If the arguments of natural theology and Christian evidences are successful, then Christian belief is warranted by such arguments and evidences for the person who grasps them, even if that person would still be warranted in their absence through the Spirit’s witness. Such a person is doubly warranted in his Christian belief, in the sense that he enjoys two sources of warrant.
Moreover, Christian apologetics may be useful and even necessary with respect to various other ends. Permit me to mention three ends with respect to which Christian apologetics plays a vital role in their realisation.
1. Shaping culture. Apologetics is useful and may well be necessary in order for the Gospel to be effectively heard in Western society today.
2. Strengthening believers. Not only is apologetics vital to shaping our culture, but it also plays a vital role in the lives of individual persons. One of those roles will be strengthening believers.
3. Evangelising unbelievers. Apologetics strengthens the faith of Christian believers.
