The power of the seed
In the parable of the sower in Matthew 13, Jesus talked about the power of the word of God to produce fruit in the heart that is in the right condition like seed that falls into good soil. So the word of God is symbolized by seed. Seed is the power that God put into creation for things to reproduce after their kind. This principle was initiated in Genesis 1 where the phrase "after his kind" appears ten times when speaking of reproduction. It also appears 7 times in Genesis 6:20 and Genesis 7:14 when talking about the animals that got onto the ark to be saved from the flood. This also shows the reproductive power God put into creation, because God only needed two of each kind of land animal on the ark. For example, there are many breeds of dogs, but the genetic code for dogs with all of its variations within its kind was saved with only two dogs on the ark. In fact, most breeds of dogs did not even exist 200 years ago. They were developed recently by selective breeding to bring out certain variations within the kind. However, there are limitations to the variations. A dog cannot give rise to anything but another dog. That is why evolution is impossible. Mutations are possible because sin damaged the original created order (Romans 8:19-23), but mutations are always a loss of genetic information and never an increase. They are almost always bad. Cancer is a genetic mutation. There is no genetic mechanism for one kind to change into another.
God also placed in man seed to reproduce after his kind (Genesis 1:28). Descendants of men are often called their seed in the Bible. God made man in His image and likeness, but sin altered this. This is reiterated in Genesis 5:1-3. Adam was made in the image and likeness of God originally, but when he reproduced, Seth was made in Adam's image and likeness. So Adam passed down his spiritual and physical flaws to his son, and down through the generations to us (Romans 5:12-21, 1Corinthians 15:21). That is why Christ came. He took the curse upon Himself as the image of God (2Corinthians 4:4, Colossians 1:15, Hebrews 1:3) to reinstate the image of God in us (Romans 8:29, 2Corinthians 3:18, Colossians 3:10). Christians are the children or seed of God (Matthew 13:38, Romans 9:8). John 3:3-5 says we must be born again, and 1John 3:9 says in the original language that the sperm of God is in His children. This "sperm" is His word (1Peter 1:23).
This principle also shows us the sobering responsibility of parents. We reproduce after our kind. What kind of parent are you? What are you reproducing in your children? We cannot control what physical DNA we pass to our children except in the spouse we choose to marry and have children with. However, we do choose what spiritual DNA we pass on. The Bible does speak of generational curses , but we should also remember that when we are born again, we are no longer under the curse. The Bible also promises that if we serve God we can stop those generational tendencies and break the cycle of sin (Deuteronomy 24:!6, 2Kings 14:6, Ezekiel 18, John 9:1-3). The power of the seed of God is greater than the power of sin.
