The Bible neither advocates nor condemns the use of birth control because it was written long before modern methods of contraception were developed. Consequently, the Bible’s silence cannot be used to argue for or against birth control’s use.
Like many issues in life, God seems to leave it up to us to decide how to honor Him in this matter. God could have plainly stated: “All families must have five children; no more, and no less.” That would have ended the issue. But He chose not to, because He allows for personal choice here. But the freedom to choose necessitates wisdom. Wise couples will take into consideration their emotional, medical, and financial limitations as they seek God’s wisdom when having children.
