Life may be understood in two dimensions: the natural and the spiritual. Humanity has studied the natural world extensively, while spiritual experience is less easily measured by empirical methods. Scripture teaches that God is Spirit and is known through faith. Hebrews 11:6 therefore says that anyone who comes to God must believe that He exists. In this sense, knowing God begins not with sight, but with trust.

That does not mean spiritual claims should never be explored. On the contrary, meaningful inquiry requires a willingness to investigate a subject according to methods appropriate to it. Just as we may initially rely on the credible testimony of someone who has traveled where we have not, the Christian invitation is to test the life of faith personally. I therefore invite you to explore for yourself whether God is real and whether a personal relationship with Him is possible.

Christian teaching also holds that human beings are accountable to God. Scripture presents a history of His dealings with humanity—how creation began, what went wrong, and His plan for restoration. To reject the invitation to know God is therefore, within this framework, comparable to rejecting the laws governing a society. Laws exist to preserve the purpose and order established by the lawgiver.

The same principle can be seen in systems generally. A functioning system operates according to rules that govern how its parts interact and produce intended results. Whether we consider the Solar System, an ecosystem, the respiratory system, or a computer system, each operates within an ordered structure. I understand this order as pointing to a Lawgiver behind the universe.

Similarly, Scripture presents the universe as God’s kingdom, governed by His principles. “The earth is the Lord’s, and the fullness thereof” (Ps. 24:1), and one central principle is that “the just shall live by faith” (Rom. 1:17; Gal. 3:11; Heb. 10:38). Throughout biblical history, God is portrayed as working through people who trusted Him and then testified to others about what they had learned.

Empirical observation is not the only way human beings acquire knowledge. Research may include both quantitative evidence and qualitative experience. In the same way, I understand knowledge of God as experiential and relational. The invitation is not to abandon reason, but to recognize that some truths are discovered through lived experience as well as observation.

The essential claim, then, is that God is known through humble trust. Those who undertake this spiritual journey may discover, as others have testified, a personal knowledge of Him. In my view, a serious search for truth should remain open to both the physical and spiritual dimensions of reality rather than dismissing either without examination.

In summary, the Christian answer is that the Creator exists and is “the beginning and the end, the first and the last.” Yet this claim is ultimately explored through a relationship of faith rather than through quantitative measurement alone. I came to this conclusion by approaching the question personally and seeking God according to the way Scripture describes. Much of what we know about people closest to us is also relational knowledge; it comes through sustained interaction rather than laboratory measurement.

Accordingly, Scripture says, “Draw near to God, and he will draw near to you” (James 4:8). Jeremiah 33:3 likewise invites us to call upon God, while Jeremiah 29:13 promises, “you will seek me and find me, when you seek me with all your heart.”
