Remember the former things of old: for I [am] God, and [there is] none else; [I am] God, and [there is] none like me, Declaring the end from the beginning, and from ancient times [the things] that are not [yet] done, saying, My counsel shall stand, and I will do all my pleasure: - Isaiah 46:9-10
God knows ends and beginnings, AND He "counsels" with Himself, AND He "decides (do all)" according to His "pleasure (purposes)"
I don't know how this verse could more clearly say that God has all things in both pre-considered and all things pre-decided. What does He look at in us? Jesus said that some he addressed were children of their father, the devil. He obviously didn't mean genetic code.
