Yes, the Bible is about the propagation of God’s seed. Unfortunately, ignorant of biblical Hebrew, Christians of all kinds fall into the trap of Neoplatonism, mishearing Genesis and Galatians by saying,  “Oh well then, it's not really about making babies; it’s about making disciples.”  
No. Definitely not. You are not an eternal god. You cannot “make” anything. Moreover, Jesus warns, when you make disciples, “you make them twice as much a child of hell as yourselves.” (Matthew 23:15)

You are flesh and blood creatures born of a mother. You have no choice in the matter, and that is the genius of the Bible. As commanded by Elohim in Genesis, you must multiply sexually like any other mammal. In every generation, you “will die…and fall like any prince.” (Psalm 82)  Cain desperately tried, but you cannot get around this through your foolish dynasties, dedicating your children to cities and monuments. 
It is the words of Elohim—his seed—not your silly eternity projects, that stand forever: 

A voice says, “Call out.” Then he answered, “What shall I call out?” All flesh is grass, and all its loveliness is like the flower of the field. The grass withers, the flower fades, when the breath of the Lord blows upon it; The people are indeed grass! The grass withers, the flower fades, but the word of our God stands forever. (Isaiah 40:6-9)
