There was seven seeds on the ark of Noah, ( Noah's seed went through one of his sons, so that seed was the same as one seed) Over the thousands of years, all seven of theses seeds went through the blood lines and ended up in Joseph and Mary which ended up in Jesus Christ. We all sprang from the 7 seeds on the ark of Noah, so my blood and your blood are a part of those seven seeds. With Jesus Blood being all seven seeds, His blood is in us all. So,... It was our blood that was spilled on the cross for our sins from the veins of Jesus Christ, our perfect sacrifice, THE LAMB OF GOD. God understood all of this before solid matter was created. He had to travel with the Hebrews to protect the seeds that would produce Jesus. He allowed the Hebrews to offer up innocent animals for a sacrifice till Jesus was born. He allowed Noah and his sons and their wives to be saved because they also carried the seeds that would produce Jesus. The whole Bible is a story of Jesus Christ and God and how he had to protect those seven seeds till Jesus was born. That is why there are so many sevens mentioned in the Bible and seven spirits of God.. We all came from those seven seeds.
Within the past 6 or 7 years, Science has just started to study about the seed of man. They don’t call them seeds but it’s the same concept as what has been recorded in the Bible for thousands of years.
