All the verses you quote have nothing to do with abortion. They merely have to do with God's foreknowledge.
No big deal! He knew us all, those whom "He chose us in Him before the foundation of the world . . ." Ephesians 1:4
Simply, He knew everything that would happen before the foundation of the world. He knew who would be born and who wouldn't. He knew who would be aborted by God Himself and others. God facilitates abortions, called spontaneous abortions, or miscarriages. God wouldn't do something sinful would He??
Anyway, God is very specific as to when a fetus becomes a living being: “The LORD God formed the man from the dust of the ground and breathed into his nostrils the breath of life, and the man became a living being” (Genesis 2:7). Adam did not become a living being until then. God breathed into the nostrils of man his spirit, which who a person really is. The body dies and returns to dust, while the spirit lives on forever.
The body is really unimportant. Flesh and blood do not inherit the Kingdom of God, it is just a housing unit to temporarily carry our spirit while we are here on earth. "For we know that if the earthly tent which is our house is torn down, we have a building from God, a house not made with hands, eternal in the heavens. For indeed in this house we groan, longing to be clothed with our dwelling from heaven" 2 Corinthians 5:1-2
