Theory: Belief Anchored in Scripture, Not Human Speculation

Theory is a set of ideas intended to explain facts or events as possibly true, but that are not known or proven to be true. Human theories shift with every generation; the Word of God does not.

Theory Versus Divine Truth

In contrast to the unfounded theories of humanistic thought, the Bible declares "Besides God there is no other", with Jesus being "the way, the truth and the life" and no one able to enter heaven apart from Him (Deut 4:35; Jn 14:6, 17:3; Act 4:12).

A theory, by its very nature, remains provisional: it must be held loosely, revised as new evidence emerges, and may one day be abandoned altogether. Divine truth is of an entirely different order. God's Word is "settled in heaven" and "the grass withers, the flower fades, but the word of our God stands forever" (Ps 119:89; Isa 40:8). What God has spoken does not need correction, updating or majority approval; it simply needs to be believed and obeyed.

Human theories likewise vary in character. Some are honest attempts to explain what men have not yet discovered, while others are deliberate attempts to exclude God from His own creation, so that "the fool has said in his heart, 'There is no God'" (Ps 14:1). People who suppress the knowledge of God become "futile in their thoughts, and their foolish hearts were darkened. Professing to be wise, they became fools" (Rom 1:21-22). The believer, by contrast, does not hold faith as a blind leap: faith is "the substance of things hoped for, the evidence of things not seen" (Heb 11:1), resting on the revealed certainty of God Himself.

Ideas compared to real-world outcomes

Scripture is the only trustworthy foundation because its Author is incapable of lying: "God is not a man, that He should lie" (Num 23:19), and it is "impossible for God to lie" (Heb 6:18). Theories change with every generation; "Jesus Christ is the same yesterday, today, and forever" (Heb 13:8). The choice before every person is therefore not between competing theories of equal weight, but between the shifting opinions of fallible humanity and the unchanging revelation of the living God.

Belief Anchored in Scripture

The Bible records, "I know who I have believed and am convinced He is able to keep what I have committed unto Him...That you may know you have eternal life" (2 Tim 1:12; 1 Jn 5:13). This is not a 'hope so' but a certain fact, with many people down through the centuries so convinced in their hearts that they have been prepared to die for Christ rather than deny Him.

Do I know I am saved or just hope so?

Our beliefs should be provable from the Bible, anchored in the truth of Scripture, not based on myths or clinging to the opinions and speculations of fallible humanity (1 Tim 1:3-4; 2 Tim 4:4; Heb 6:19). Do not be deceived and accept human theories, ideas and predictions as trustworthy while questioning or dismissing the Word of God.

The humanistic theory of evolution claims that complex living creatures, including humanity, gradually developed from simpler forms of life over vast ages of time. The Bible teaches something entirely different: that God created all the creatures of the world, each "according to its kind", by the power of His word (Gen 1:20-25; Ps 33:6,9), and that He made humans as they are – not ascended from animals, but formed as the crown of creation, made male and female in His own image (Gen 1:26-27), with man formed from the dust of the ground and animated directly by the breath of God (Gen 2:7).

Where evolution requires blind chance and millions of unobserved years, Scripture declares that "by Him all things were created that are in heaven and that are on earth" (Col 1:16; Jn 1:3), and that the work of creation was completed in six days, with everything deemed "very good" (Gen 1:31; Exod 20:11). "By faith we understand that the worlds were framed by the word of God" (Heb 11:3) – a certainty that no theory of human origin can overturn.

God desires all people to come to recognise Him, for He reveals His love to humanity: while we were yet sinners Christ died for us, and He wants all people to be saved – yet because He will not override our free will, this will not be the case (Josh 4:24; Ps 145:12; Rom 5:8; 1 Tim 2:4).

From Theory to Practice

Merely to know about a thing is not sufficient. A Christian theorist will make little headway in spiritual living – it must be applied. The principle or lesson must be outworked in the real world. Knowing about a concept or discussing its value is only the first step – the outworking is the all-important next step; we are told to "be doers of the Word" (Jas 1:22).

Jesus ended the Sermon on the Mount with precisely this warning: whoever hears His words and does them is like "a wise man who built his house on the rock", while whoever hears them and does not do them is like "a foolish man who built his house on the sand", and its fall was great (Mt 7:24-27). Knowledge that never reaches the feet provides no foundation when the storms come. Similarly, the apostle Paul cautions that "knowledge puffs up, but love edifies" (1 Cor 8:1) – truth grasped but never practised breeds pride rather than Christlikeness.

Believe in it strongly enough to take action

The practical outworking of belief is a daily discipline: "Be doers of the word, and not hearers only, deceiving yourselves" (Jas 1:22). Timothy was urged to "be diligent to present yourself approved to God...rightly dividing the word of truth" (2 Tim 2:15), and all believers to "grow in the grace and knowledge of our Lord and Savior Jesus Christ" (2 Pet 3:18). Growth in grace and growth in obedience always travel together: as belief settles deeper into the heart, it must show itself in speech, conduct, priorities and love – otherwise it remains information, never transformation.
