I did answer your question. You asked about genetic variation and random mutation. I told you that genetic variation is produced by mutations in a random manner.
Are you suggesting that God has no control over random processes? That “random” is synonymous for “out of God's control”?
Prov 16:33 The dice are cast into the lap but every result is from the Lord.
As to your ‘miraculous’ ideas of how evolution works, do you feel a “miracle” is needed for random variation and selection to produce novel molecular machines?
Did you not read what I posted to you about “directed evolution”?
Do you suppose that miraculous intervention is needed for this process to derive novel and useful proteins for industrial purposes?
No. I am absolutely not saying that, allmendream. God uses what we view as "randomness" for achieving His creative purposes in Nature. Broadly speaking, "randomness" refers to the potentiality of newness arising in nature. And "newness" arises in biological beings literally with each and every time-step.
In short, God loves "random!" It's what keeps the universe from becoming perfectly static; of allowing for its development; in leaving room for, among other things, human free will.
But because the total system contains random elements (potentialities) does not mean that the total system is "unguided," let alone purposeless.
