For example, in Lev. 19:19, it says that "You are not to breed cattle with a diverse kind." Many Christians have seen this verse applied to hybrid cattle, livestock and pets. However, it also seems relevant to mixing human and animal DNA or human and plant DNA, which is now being done in private laboratories.
It is amazing and interesting to me how the Bible applies to these high tech science endeavors and thereby helps guide us in our choice of work and career. It also helps us know how to vote and inform our civil magistrates with regard to these matters.
I have a Christian friend in Minnesota (John Mesko) who was an Extension Agent for Purdue University, then worked for Dow Chemical. He tells of the true story of him being in a meeting where the Dow corn genetic researchers were reporting on the anti-fertility results of a new strain of genetically modified corn. It was hailed by Dow Chemical leaders as a breakthrough in GMO corn because it could be fed to people in third world countries to reduce the population in the next generation. As a result of this, John Mesko left Dow Chemical and now runs Lighthouse Farm. He presented these details at a home school convention in Fargo, ND a few years ago.
This is opposite to what God wants. God wants parents to have their quivers full of children!
Lo, children are an heritage of the LORD: and the fruit of the womb is his reward.
As arrows are in the hand of a mighty man; so are children of the youth.
Happy is the man that hath his quiver full of them: they shall not be ashamed, but they shall speak with the enemies in the gate. Psalm 127
