Using the Word

In the midst of crafting a Gospel presentation on December 17th, I was debating how much to quote from the Bible. The problem is that by appealing to the Bible, I am open to the claim that the Bible is not true. On the other hand, the Bible expresses certain facts about the world and human condition which are true.
In the end, I arrived at the following:
1) Faith comes by hearing and hearing by the Word of God. (Rom 10)
2) The Holy Spirit helps us to understand the Word of God. (1 Cor)
3) By simple observation, I do not know who is under the conviction of the Holy Spirit
4) Therefore, if I share directly from God's Word, it is possible that some may come to Faith through the work of the Holy Spirit.

From John Frame's Essay:
"Indeed, there is a sense in which all of the unbeliever's thinking is Christian. Christian presuppositions are the only way to think. The alternative is not thought but meaninglessness." Put in a trite way - "All truth is God's truth."

We cannot argue for the truth of Christianity using principles from relativism, pluralism, naturalism, or any other false worldview. But that is not because we simply assume Christianity, but because those views are demonstratably false!

If by 'Christian Presuppositions' we mean 'True Presuppositions' then there is no argument. Obviously, we should never knowingly argue using false presuppositions.

However, not all truth is distinctly Christian. Truths of logic, history, and empirical science can be observed and discussed correctly by Christians and non-christians alike. Sometimes there is disagreement on these truths, but they can all be argued apart from understanding that Jesus is God. At most, discussion at this level may lead to theism, but belief in God is a far cry from Christianity.

Then there are other truths, spiritual truths, that are distinctly Christian. These distinctives must be explained and defended in any arguement, though we can still claim and not deny them in an argument.
