The ancient Israelites were especially concerned about bringing forth children because of God’s promise to make them a mighty nation and because through them would come the seed of Abraham by means of whom all the families of the earth would bless themselves. (Ge 28:14) Having many children was considered a blessing from God. (Ps 127:3-5; 128:3-6) Sterility was looked on as a reproach.—Ge 30:23.
Now a days there are some who refrain from having children but this must be done for the right reason. For example, some Jehovah's Witness do the following:
Joy and Responsibility
Jehovah’s people recognize that while there is joy in rearing children, there is also responsibility. The Bible, at 1 Timothy 5:8, says: “Certainly if anyone does not provide for those who are his own, and especially for those who are members of his household, he has disowned the faith and is worse than a person without faith.”
Parents must provide for their families both materially and spiritually, and this takes considerable time and effort. They do not have the attitude that since God provides children, it is left to God to care for them. They realize that rearing children according to Bible principles is a full-time responsibility assigned by God to parents; it is not one that should be delegated to others.—Deuteronomy 6:6, 7.
The task of rearing children is especially difficult in these “last days” of “critical times hard to deal with.” (2 Timothy 3:1-5) Apart from worsening economic conditions, the increasing godlessness of society adds to the challenges of child rearing today. Even so, throughout the world, countless Christian couples have taken up this challenge and are successfully rearing godly children “in the discipline and mental-regulating of Jehovah.” (Ephesians 6:4) Jehovah loves and blesses these parents for their hard work.
Why Some Remain Childless
Many Christian couples, on the other hand, do not have children. Some are infertile and yet do not adopt children. Other couples who have the ability to produce offspring decide not to do so. Such couples do not remain childless because they shirk responsibility or are afraid to meet the challenges of parenthood. Rather, they have determined to give their full attention to different avenues of the full-time ministry that the rearing of children would not allow. Some serve as missionaries. Others serve Jehovah in the traveling work or at Bethel.
Like all Christians, they realize that there is an urgent work to do. Jesus said: “This good news of the kingdom will be preached in all the inhabited earth for a witness to all the nations; and then the end will come.” This work is being done today. It is a vital work, since “the end” will mean destruction for those who have not heeded the good news.—Matthew 24:14; 2 Thessalonians 1:7, 8.
Ours is a period similar to the time when Noah and his family constructed the gigantic ark that preserved them through the great Flood. (Genesis 6:13-16; Matthew 24:37) Although Noah’s three sons were all married, none fathered children until after the Deluge. One reason for that may have been that these couples wanted to devote their full attention and energy to the work at hand. Another may have been reluctance to bring children into a debased and violent world where “the badness of man was abundant . . . and every inclination of the thoughts of his heart was only bad all the time.”—Genesis 6:5.
While this does not imply that it is wrong to have children today, many Christian couples decline to have children so as to become more fully involved in the urgent work that Jehovah has given his people to do. Some couples have waited for a time before having children; others have decided to remain childless and consider the possibility of bearing children in Jehovah’s righteous new world.
In regards to Birth Control, JW have also published some articles that are based on the Bible. Email me and I will send them to you. There is even some articles that talk about sterilization. These articles where intended for Jehovah's Witness but anyone who is not a JW can still benefit from the council there given that they are based on the Bible. So email me and I wil give you more information.
There is a lot more to consider on this subject.
If you would like to know more about this and other themes, next time Jehovah's Witness come to your door, ask them for a free Bible study at your convenience. You will never regret all the knowledge you will acquire and remember that what you do with that knowledge is your choice.
