Christian Apologetics, Part 4 (of 4)

I distinctly remember the first time I walked into a courtroom and heard the bailiff swear in a witness. The words of the oath and the profound promise that stands behind it deeply impressed me.

I solemnly swear to tell the truth, the whole truth, and nothing but the truth. So help me, God. 

Christians believe that the ultimate source of all truth and reality is the Triune God: Father, Son, and Holy Spirit. At the heart of the faith is the truth-claim that Jesus Christ, the second person of the Trinity, took to himself a human nature and became the God-Man. During his earthly journey into human history, Jesus said: "I am the way and the truth and the life" (John 14:6). He identified himself as none other than Truth Incarnate.

According to historic Christianity, God reveals his Truth and truths through his "two books." The first book is the metaphorical book of nature (God's created world). The second book is the literal book of Scripture (God's written Word). These two revelatory books are meant to affirm and complement one another. When both books are understood correctly they will never contradict, because all truth is God's truth.

As the Creator and Sustainer of the universe, God has revealed truth in science, logic, mathematics, morality, history, philosophy, the arts, and various other areas. When a person apprehends the truth in any field or discipline they are not far away from God's fingerprint because God is the source of all truth.

In light of these divinely revealed truths about God, Christians place a high value on learning truth. Believers should pursue the truth in all things and never settle for anything else.

Living and Walking in the Truth

Imagine the impact if a follower of Jesus Christ were to prize truth. That person's character and reputation would inevitably be transformed. The person would carry an impressive intellectual, moral, and spiritual authority because of his or her regard for truth. Imagine, too, what would happen if non-Christians came to view Christians as people who love, value, and pursue truth at any cost.

One of the terrible things about being fallen sinners is that we have a strong propensity to run from the truth and to suppress it (Romans 1:18). But God's active grace makes it possible for his children to grow in a love of the truth and to be transformed by it.

The pursuit and defense of truth is at the forefront of the Christian world-and-life view. And contending for that revealed truth is the calling of every apologist (Jude 3)–whether novice or expert.
