The part left out of the parable of the various soils was the preparation of the soil to begin with. The 7th year Sabbath for the field that the seed was sewn into.
Meaning that God was diligently working for the salvation of your precise soul 6 generations before you were born. (Many of us have a hard time tracing our ancestors that far back)
But God was causing babies to grow up to marry specific people to give you your precise genetics AND those who would eventually cause you to seek Him for yourself. That's a lot of finagaling...just to get you and not get caught manipulating anyone anywhere.
God was never into this exercise of Earth's creation for the numbers....just the best of the best believers (whose identities are always shocking and a surprise)

Not exactly the way most people would go about doing things....but we aren't God now are we?
