Imagine a conversation like the following to occur:

Tom: “I don’t believe God exists!”
Mike: “The Bible says He does.”
Tom: “Well, am I expected to accept the Bible as God’s word, when I don’t believe he exists?”
Mike: “Yes.”
Tom: “Prove to me he does!”

How would you go about doing this? Here is a suggested starting place: Hebrews 3:4, For every house is builded by some one; but he that built all things is God (ASV).
As you consider the passage, think about what it is saying. First, physical things are made by one that is greater than the thing (or things) made. Second, the planet on which we live is a material thing (within a physical universe). Third, it was God who built all things. In the beginning God created the heavens and the earth (Genesis 1:1).
Here is a logical argument from the above paragraph, an argument that is very old, but still very relevant. It goes like this: 1) Whatever begins to exist, has a cause for its existence (i.e. something or someone brought it into existence), 2) The universe began to exist (i.e., the physical/material universe was brought into existence), 3) Therefore, the universe has a cause (God). In formal logic, this is known as a valid (properly structured) argument. The first premise has two components, the first is an antecedent (whatever begins to exist) followed by the consequent (has a cause for its existence). If the antecedent is true, the consequent follows.

From the argument we learn of that which begins to exist has a cause. We know from science the material universe had a beginning. Without regard to what the Bible says on the matter of creation, let us note this scientific opinion, “According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.8 billion years ago.” Evolutionary scientists have a great problem with the word born because it means “began to exist.” Thus, this material/physical universe must have a cause for its existence. Evolutionary scientists go from measuring or testing in the material realm into a leap of faith realm of “anything-but-God” religious belief.
In other words, they can offer no substantive counter to theistic reply of “God” as the cause of the material universe. What is offered is subject to ridicule and mockery; their “anything-but-God” religious belief becomes obvious.

You may not feel like you can adequately give attention to proving God’s existence but remember the Holy Spirit did give attention to the topic. When you think about fear associated with making the case for God’s existence, let there be no fear or apprehension. Reflect on the Holy Spirit’s words in Hebrews 3:4; remember that every house has its builder. RT
