God commanded Adam and Eve to be fruitful and multiply (Gen. 1:28). However, that command in no way obviated the need for intelligent planning and birth control. The Bible does not condemn family planning.
By focusing attention on the population explosion, there is a need to get across the seriousness of the overpopulation dilemma — and resulting famine — facing mankind. However, I am not necessarily espousing human solutions that others may advance. Rather, I mean to show that man cannot effectively solve the problem as long as he is largely motivated by selfishness, greed and vanity.
Children are a heritage of God (Ps. 127:3). All married couples should intelligently plan — unless there are extenuating circumstances — to have children. However, it is also plain that God never intended man to procreate like a mindless animal.
Man’s mind is patterned after the mind of God Himself — in whose physical and mental image man was created. Man’s mind should be exercised toward the intelligent direction in every facet of life.
The cost of caring for children also enters the picture. Paul told Timothy: “But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel” (I Tim. 5:8). And, “A good man leaveth an inheritance to his children’s children [grandchildren] …” (Prov. 13:22).
If a married couple has more children than the family head can comfortably support, the children may never reach their full potential in later life.
