God reveals His truth in us in two great books—the Holy Book and the Book of Nature. The former is His special revelation and the latter, His general revelation.
“All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works” (2Ti 3:16-17).
“The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day utterethspeech, and night unto night sheweth knowledge” (Psa 19:1-2).
We can learn much from observing this material universe in which we exist; we can see beyond all reasonable doubt some of the attributes of the Creator. But as Christians, the Word of God is our sole authority and the basis for our understanding of reality.
Turning to the Bible, we find that nature and revelation, instead of contradicting each other as some skeptics claim, actually harmonise beautifully. Take the creation account in the book of Genesis, for instance. Scientific observations and philosophical thinking have only backed the prima facie case for God’s special revelation.
On the matter of human sexuality, both the Word of God and the creation of God reiterate His design and original order. The dignity of human sexuality is very well defined for us in both the Holy Book and the Book of Nature.
Among the lessons we learn from the creation account in Genesis is that God created human beings as social creatures. We are individuals, yes; but we are not meant to exist in isolation. We are meant to exist in societies, and the most basic of societies is the family.
Genesis reveals that heterosexual marriage is the foundation and basic nature of family relationships.This is a fact we observe from nature as well since the beginning of human history.
“So God created man in his own image, in the image of God created he him; male and female created he them” (Gen 1:27).
“And Adam said, Thisis now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man. Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh” (Gen 2:23-24).
The Lord Jesus affirms this divine pattern.
“And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh? Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder” (Mat 19:4-6).
Heterosexual union is also the natural means by which new life is formed. God told the man and the woman to ‘Be fruitful, and multiply” (Gen 1:28).This fact is undeniable. For anyone who rejects the Holy Book, the Book of Nature proves this beyond all contention.
Two males can never produce offspring, just as two females cannot. It is so with every species of animals. Human beings too are created male and female for the purpose of procreation. This is a simple, scientifically observable biological fact.
Sex is created by God not only for procreation but also for pleasure.Song of Solomon 4-5 reveals that sexual pleasure is part of God’s design for marriage. But sexual activity is not a free-for-all;it is conditional. Sex, as God designs it, is allowable only in a monogamous, heterosexual marriage.
Christians need not be priggish about the pleasure of sex. It is a gift of God for a man and woman married to each other to enjoy. We either teach our children God’s design for sexuality from the Bible, or they will learn from the lies generated by Hollywood and the mass media.
The creation account provides important truths for sexuality and sexual behaviour because it reveals nature’s original order before sin entered the picture. “And God saw every thing that he had made, and, behold, it wasvery good” (Gen 1:31).
But beyond the physical aspect, marriage is symbolic of something more significant. In the Old Testament, God used unfaithfulness in marriage as an analogy to describe Israel. “Surely as a wife treacherously departeth from her husband, so have ye dealt treacherously with me, O house of Israel, saith the LORD” (Jer 3:20).
In the New Testament, the husband-wife relationship is again used to illustrate the relationship between Christ and His church.
“Wives, submit yourselves unto your own husbands, as unto the Lord. For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body…Husbands, love your wives, even as Christ also loved the church, and gave himself for it…For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. This is a great mystery: but I speak concerning Christ and the church. Nevertheless let every one of you in particular so love his wife even as himself; and the wife see that she reverence her husband” (Eph 5:22-23, 25, 31-33).
Both the Holy Book and the Book of Nature define what human sexuality is—its nature, purposes and confines. Man cannot break God’s law as revealed in Scripture and nature. Man will only break ourselves if we attempt to do so.
