The Bible does not explicitly mention modern birth control methods, but it gives principles that can guide decisions in this area. One of the few passages that touches on intentionally preventing conception is found in Genesis 38:9-10, where Onan, commanded to provide offspring for his deceased brother’s wife, “spilled his seed on the ground.” It says, “But the thing which he did displeased the Lord; therefore He killed him also.” Onan’s sin was not merely the act itself, but his rebellion against God’s command and his selfish motive.
Children are consistently described as blessings from the Lord. Psalm 127:3-5 says, “Behold, children are a heritage from the Lord, the fruit of the womb is a reward.” The Bible never portrays childbearing as a burden or curse.
However, Scripture also honors wisdom and self-control. Proverbs 21:5 commends the plans of the diligent. In 1 Corinthians 7:5, Paul speaks of couples mutually agreeing to abstain for a time for prayer and fasting, which indirectly affirms the concept of intentionality in the marital relationship.
The heart motive is key. If birth control is used out of selfishness, fear, or a rejection of God’s design for family, it becomes sin. If it is used prayerfully, with a desire to steward family life wisely before God, there may be liberty, though this must always be approached with reverence and a yielded heart.
